Second generation (2G) wireless data networks in Japan deliver datarates up to 9.6 kbps for upload and up to 29.8 kbps for download. 3DES - Triple Data Encryption Standard 3DNS - is a wide area load balancer from F5 Networks. The 3DNS Controller is a high availability, intelligent load balancing solution for geographically distributed Internet sites and data centers. 3DNS manages and distributes user requests across multiple, redundant server sites – regardless of the platform type or combination and without requiring additional software on the servers. User requests are distributed according to factors such as round trip time, number of active servers, packet loss, etc. and, the 3DNS Controller can be configured to make traffic distribution decisions according to what is most important for an organization’s network. - it takes a request (for a web site for instance) and looks at the best route to get there. What is 3-DNS? - Networking - DSLReports Forums 3DNS - F5 3DNS configuration - DevCentral - F5 Networks Using F5's BigIP and 3DNS for Failover and DR routing - PDF See also: BIG-IP 3G - Third generation (3G) wireless networks in Japan deliver datarates on the order of 64 kbps for upload and on the order of 200 kbos for downlad. These higher speeds allow the transmission of video and two-way video telephony. Other data connections, e.g. download of information or JAVA applets, are also several times faster on 3G networks then on older 2G networks. In Japan there are three parallel, independent and competing 3G networks. In U.S, 3G currently (12/03) supports 300 to 500 kilobits per second, with bursts up to 2 mbps. 3GPP - Third Generation Partnership Project (3GPP) is a collaboration agreement that was established in December 1998. The collaboration agreement brings together a number of telecommunications standards bodies which are known as "Organizational Partners". The current Organizational Partners are ARIB, CCSA, ETSI, ATIS, TTA, and TTC. The original scope of 3GPP was to produce globally applicable Technical Specifications and Technical Reports for a 3rd Generation Mobile System based on evolved GSM core networks and the radio access technologies that they support (i.e., Universal Terrestrial Radio Access (UTRA) both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes). The scope was subsequently amended to include the maintenance and development of the Global System for Mobile communication (GSM) Technical Specifications and Technical Reports including evolved radio access technologies (e.g. General Packet Radio Service (GPRS) and Enhanced Data rates for GSM Evolution (EDGE)).

Third-Generation Partnership Project 2 is a collaborative effort for Generating 3G specifications for providing high-speed IP-based mobile systems. It was established for developing global specifications for network evolution from ANSI/TIA/EIA-41 to 3G, and global specifications for the radio transmission tehcnologies supported by ANSI/TIA/EIA-41. 3GPP2 is mainly supported in North America, China, Japan and South Korea and continues to play a dominant role in bringing IP technology to these cellular markets. 3GPP2 was born out of the International Telecommunication Union (ITU) International Mobile Telecommunications-2000 (IMT-2000) initiative for providing high-speed data over the wireless network. Although discussions did take place between ETSI and the ANSI-41 community to consolidate collaboration efforts for 3G, in the end it was deemed appropriate to establish 3GPP2 as a parallel partnership project.

Click here for more 480I information 4G - At present the download speed for imode data is limited to 9.6 kbit/sec which is about 6 times slower than an ISDN fixed line connection. With 504i handsets the download data rate was increased 3-fold to 28.8kbps. However, in actual use the data rates are usually slower, especially in crowded areas, or when the network is "congested". For third generation mobile (3G) data rates are 384 kbps (download) maximum, typically around 200kbps, and 64kbps upload since spring 2001. Fourth generation (4G) mobile communications will have higher data transmission rates than 3G. 4G mobile data transmission rates are planned to be up to 20 megabits per second.

Big Data - big data is a collection of data sets so large and complex that it becomes difficult to process. Big Data - lots of information about big endian - Most Significant byte first, 1122h stored as 1122h, Motorola 68k and SUN format. big-endian adj. [common; From Swift's "Gulliver's Travels" via the famous paper "On Holy Wars and a Plea for Peace" by Danny Cohen, USC/ISI IEN 137, dated April 1, 1980] 1. Describes a computer architecture in which, within a given multi-byte numeric representation, the most significant byte has the lowest address (the word is stored `big-end-first'). Most processors, including the IBM 370 family, the PDP-10, the Motorola microprocessor families, and most of the various RISC designs are big-endian. Big-endian byte order is also sometimes called `network order'. See little-endian, middle-endian, NUXI problem, swab. 2. An Internet address <../i/Internet_address.html> the wrong way round. Most of the world follows the Internet standard and writes email addresses starting with the name of the computer and ending up with the name of the country. In the U.K. the Joint Networking Team had decided to do it the other way round before the Internet domain standard was established. Most gateway sites have ad-hockery <../a/ad-hockery.html> in their mailers to handle this, but can still be confused. In particular, the address could be interpreted in JANET's big-endian way as one in the U.K. (domain uk) or in the standard little-endian way as one in the domain as (American Samoa) on the opposite side of the world. BIG-IP - an F5 Networks "BIG-IP product suite is a system of application delivery services that work together on the same best-in-class hardware platform or software virtual instance.

BIRT - Build Integration Release Testing BIS - Boot Integrity Service BIST - Built-In Self Test (hardware feature) bit - n. [from the mainstream meaning and `Binary digIT'] 1. [techspeak] The unit of information; the amount of information obtained by asking a yes-or-no question for which the two outcomes are equally probable. 2. [techspeak] A computational quantity that can take on one of two values, such as true and false or 0 and 1. 3. A mental flag: a reminder that something should be done eventually. "I have a bit set for you." (I haven't seen you for a while, and I'm supposed to tell or ask you something.) 4. More generally, a (possibly incorrect) mental state of belief. "I have a bit set that says that you were the last guy to hack on EMACS." (Meaning "I think you were the last guy to hack on EMACS, and what I am about to say is predicated on this, so please stop me if this isn't true.") "I just need one bit from you" is a polite way of indicating that you intend only a short interruption for a question that can presumably be answered yes or no. A bit is said to be `set' if its value is true or 1, and `reset' or `clear' if its value is false or 0. One speaks of setting and clearing bits. To toggle or `invert' a bit is to change it, either from 0 to 1 or from 1 to 0. See also flag, trit, mode bit. The term `bit' first appeared in print in the computer-science sense in a 1948 paper by information theorist Claude Shannon, and was there credited to the early computer scientist John Tukey (who also seems to have coined the term `software'). Tukey records that `bit' evolved over a lunch table as a handier alternative to `bigit' or `binit', at a conference in the winter of 1943-44. bitblit - (BIT BLock Transfer) In computer graphics, a hardware feature that moves a rectangular block of bits from main memory into display memory. It speeds the display of moving objects (animation, scrolling) on screen. A hardware bitblt provides fastest speed, but bitblts are also implemented in software even in non-graphics systems. For example, text scrolls faster when it is copied as a contiguous block (bitblt) to the next part of the window rather than processing every character on every line. See stretch blt.

The Test for Homogeneity answers the proposition that several populations are homogeneous with respect to some characteristic. The Test for independence (one of the most frequent uses of Chi Square) is for testing the null hypothesis that two criteria of classification, when applied to a population of subjects are independent. If they are not independent then there is an association between them. Chi Square is the most popular discrete data hypothesis testing method.

There is often more than one CODEC for a particular format, so the phrase encoding method is often used when referring to a particular compressed format. Format is often used instead of encoding method. An algorithm or set of algorithms that both compress and expand data (and decompress). The data might be sound, video or just plain data. Data compression often causes a loss of data, which can be very noticeable. or not. usually, the less loss there is of data, the larger the file size. These Codecs are used to allow either faster transmission of data, or smaller sized files or both. Codecs can also include encryption.

CVS - Custom Volume Size CWDM - Coarse WDM. "In 2002 the ITU standardized a channel spacing grid for use with CWDM (ITU-T G.694.2), using the wavelengths from 1270 nm through 1610 nm with a channel spacing of 20 nm. (G.694.2 was revised in 2003 to shift the actual channel centers by 1, so that strictly speaking the center wavelengths are 1271 to 1611 nm). Many CWDM wavelengths below 1470 nm are considered "unusable" on older G.652 specification fibers, due to the increased attenuation in the 1270–1470 nm bands. Newer fibers which conform to the G.652.C and G.652.D[2] standards, such as Corning SMF-28e and Samsung Widepass nearly eliminate the "water peak" attenuation peak and allow for full operation of all 18 ITU CWDM channels in metropolitan networks." Coarse WDM - Wikipedia The Ethernet LX-4 10 Gbit/s physical layer standard is an example of a CWDM system in which four wavelengths near 1310 nm, each carrying a 3.125 gigabit-per-second (Gbit/s) data stream, are used to carry 10 Gbit/s of aggregate data. The main characteristic of the recent ITU CWDM standard is that the signals are not spaced appropriately for amplification by EDFAs. This therefore limits the total CWDM optical span to somewhere near 60 km for a 2.5 Gbit/s signal, which is suitable for use in metropolitan applications. The relaxed optical frequency stabilization requirements allow the associated costs of CWDM to approach those of non-WDM optical components.

The non-conformance to intended usage requirement. degraded mode - The condition in which a RAID system operates when a component has failed. Click here for more info Degree of Freedom - Degrees of freedom are the equivalent of currency in statistics - you earn a degree of freedom for every data point you collect, and you spend a degree of freedom for each parameter you estimate. Since you ususally need to spend 1 just to calculate the mean, you then are left with n-1 (total data points "n" - 1 spent on calculating the mean). Demand caching - A performance caching technique in which the currently requested data is read in anticipation of another request before its allocated blocks are recycled. Reassignment of the blocks is done on the basis of least recently used (LRU). demote primary LU - primary LU becomes a secondary LU for the mirror. LU no longer accessible by production host. dense mode multicast - multicasts to every router and node.

ETL - extract, transform, load = In managing databases, extract, transform, load (ETL) refers to three separate functions combined into a single programming tool. First, the extract function reads data from a specified source database and extracts a desired subset of data. Next, the transform function works with the acquired data - using rules or lookup tables, or creating Combinations with other data - to Convert it to the desired state. Finally, the load function is used to write the resulting data(either all of the subset or just the changes) to a target database, which may or may not previously exist. ETL can be used to acquire a temporary subset of data for reports or other purposes, or a more permanent data set may be acquired for other purposes such as: the population of a data mart or data warehouse; conversion from one database type to another; and the migration of data from one database or platform to another.

FC-AL - same as FCAL FCAPS - ISO fault-management, configuration, accounting, performance, and security) is an acronym for a categorical model of the working objectives of network management. There are five levels called: the fault-management level (F), the configuration level (C), the accounting level (A), the performance level (P), and the security level (S). At the F level, network problems are found and corrected. Potential future problems are identified, and steps are taken to prevent them from occurring or recurring. In this way, the network is kept operational, and downtime is minimized. At the C level, network operation is monitored and controlled. Hardware and programming changes, including the addition of new equipment and programs, modification of existing systems, and removal of obsolete systems and programs, are coordinated. An inventory of equipment and programs is kept and updated regularly. At the A level, which might also be called the allocation level, is devoted to distributing resources optimally and fairly among network subscribers. This makes the most effective use of the systems available, minimizing the cost of operation. This level is also responsible for ensuring that users are billed appropriately. The P level is involved with managing the overall performance of the network. Throughput is maximized, bottlenecks are avoided, and potential problems are identified. A major part of the effort is to identify which improvements will yield the greatest overall performance enhancement. At the S level, the network is protected against hackers, unauthorized users, and physical or electronic sabotage. Confidentiality of user information is maintained where necessary or warranted. The security systems also allow network administrators to control what each individual authorized user can (and cannot) do with the system.

See Embedded / Firmware for more information FWB - Fixed Wireless Broadband FWH - firmware hub (a chip/hub used to store the BIOS codes) (Courtesy of and phil7890 FWH are SPI are typically thought of as chips (some insist it's a hub). This is used to store the BIOS firmware/codes. For example, the Phoenix/Award BIOS or AMI BIOS (or other equivalent BIOS) codes are stored in this FWH or SPI serial chip. The brand on the FWH is typically SST, Atmel, Intel or Winbond. However with the Winbond brand we'll have to be careful as they make many other types of chips too (not just memory chips - but their other chips typically have a lot of pins, ie. more than 32 for a FWH). The FWH is usually a 32-pin PLCC chip. Most/some of the time it'll be sitting in a socket so that it's removable if anybody wants to do this. It'll typically have a 29-something part number. (from LPC, FWH And SPI Used In Bios Rom?) If we can't find a 32-pin FWH (PLCC chip with or without socket), then we'll have to look for an 8-pin chip of those similar brands. The part number is typically 25-something or 45-something, etc. The SPI chip is normally 8-pin, and it is sometimes found on recent motherboards using the Intel 965 or newer chipsets. It is normally soldered down - without a socket. The FWH is usually a 32-pin PLCC chip. 1. Yes we can regard the 32-pin PLCC as a BIOS ROM chip but this as long as it's a memory/flash/EE type of chip. 2a. It's usually the south bridge chip (I/O controller hub) where the BIOS chip (LPC/FWH/SPI) connects to, ie. it's like a leaf of its own and hanging off this south bridge branch. From the south bridge chip, various other items connect to/out from here. 2b. As for the LPC bus itself, some items such as the BIOS chip, Super I/O (multifunction) chip, optional TPM/security chip, and other ~low-speed/ bandwidth chips can be found here. 3a. We normally don't hear anything called HPC (high pin count) on a motherboard but there are various chips with lots of pins. There's HPC for a high-performance something-else though. 3b. It's usually in the microcontroller world (for example, the PIC stuff) where we find this HPC term. It's because the PIC originally came with a few pins and over the years they added many more general-purpose I/O pins. - Courtesy of: phil7890 FWSM - firewall services module (Cisco) - DSL running on copper telephone wires, can run at GIGABITE/second speeds = Lowly DSL (running on copper wires) will get GIGABIT speed boost G.SHDSL - Also known as G.991.2, G.SHDSL is an international standard for symmetric DSL developed by the ITU.

GA - General Availability GAMP - Good Automated Manufacturing Practices gang-of-four - Erich Gamma, Richard Helm, Ralph Johnson, John Vlissides Gang Trespass - Source LUs and their associated Snapshot LUs must be owned by the same SP. If a source LU is trespassed, any associated Snapshot LU must also implicitly be trespassed. The same is also true if the Snapshot LU is trespassed. A design of how Gang Trespass will be implemented was agreed to in a meeting with Dave Harvey and Jim Cook in SOBO. Details of this implementation will be released by them and implemented in time for SnapView Phase 2 qualification Gantt Chart - A Gantt chart is a powerful and preferred visual reporting device used for conveying a project's schedule. A typical Gantt chart graphically displays the work breakdown, total duration needed to complete tasks, as well as %completion. The Gantt chart itself will not display level of effort, and is not an effective planning tool on its own. Today, Gantt Charts may be integrated with other spreadsheet-type reporting devices that convey additional information related to project planning. Furthermore, Gantt Charts are often enhanced with functionality that includes the identification of relationships between tasks, and the ability to dynamically change task attributes. gap analysis - something in QA coverage ?? perhaps, analysis of missing coverage? GARP - Generic Attribute Registration Protocol. GARP was originally designed to to facility multicast filtering at the MAC layer. GARP was generalized and two trivial applications were designed on top of GARP: 1] the GARP VLAN Registration Protocol (GVRP), and 2] the GARP Multicast Registration protocol (GMRP). The only difference: GMRP manipulates 48-bit multicast MAC addresses, while GVRP handles 12-bit VLAN IDs.

GVRP - the GARP VLAN Registration Protocol gw - GateWay (router) GWT - Google Web Toolkit Google Web Toolkit - Wikipedia Google Web Toolkit — Google Developers H.225 - ITU-T : Series H H.225.0 v2 is a standard which covers narrow-band visual telephone services defined in H.200/AV.120-Series Recommendations. It specifically deals with those situations where the transmission path includes one or more packet based networks, each of which is configured and managed to provide a non-guaranteed Quality of Service (QoS) which is not equivalent to that of N-ISDN such that additional protection or recovery mechanisms beyond those mandated by Rec. H.320 is necessary in the terminals. H.225.0 describes how audio, video, data, and control information on a packet based network can be managed to provide conversational services in H.323 equipment. The structure of H.225 follows the Q.931 standard H.235 - H.235 provides enhancements within the framework of the H.3xx-Series Recommendations to incorporate security services such as Authentication and Privacy (data encryption). H.235 should work with other H series protocols that utilize H.245 as their control protocol. All H.235 messages are encrypted as in ASN.1. H.245 - H.245 is line transmission of non-telephone signals. It includes receiving and transmitting capabilities as well as mode preference from the receiving end, logical channel signalling, and Control and Indication. Acknowledged signalling procedures are specified to ensure reliable audiovisual and data communication. H.245 messages are in ASN.1 syntax. They consist of an exchange of messages. MultimediaSystemControlMessage message types can be defined as request, response, command and indication messages. The following additional message sets are available: Master Slave Determination messages Terminal capability messages Logical channel signalling messages Multiplex Table signalling messages Request Multiplex Table signalling messages Request Mode messages Round Trip Delay messages Maintenance Loop messages Communication Mode Messages Conference Request and Response Messages TerminalID Commands and Indications H.248 - H.248 - a Control Protocol Stack coupling. See also MGCP H.261 - H.261 describes a video stream for transport using the real-time transport protocol, RTP, with any of the underlying protocols that carry RTP. H.263 - H.263 specifies the payload format for encapsulating an H.263 bitstream in the Real-Time Transport Protocol (RTP). Three modes are defined for the H.263 payload header. An RTP packet can use one of the three modes for H.263 video streams depending on the desired network packet size and H.263 encoding options employed. The shortest H.263 payload header (mode A) supports fragmentation at Group of Block (GOB) boundaries. The long H.263 payload headers (modes B and C) support fragmentation at Macroblock (MB) boundaries. For each RTP packet, the RTP fixed header is followed by the H.263 payload header, which is followed by the standard H.263 compressed bitstream. The size of the H.263 payload header is variable depending on the modes. H.323 - H.323 Protocol The H.323 standard provides a foundation for audio, video, and data communications across IP-based networks, including the Internet. H.323 is an umbrella recommendation from the International Telecommunications Union (ITU) that sets standards for multimedia communications over Local Area Networks (LANs) that do not provide a guaranteed Quality of Service (QoS). H.323 is generally modeled after PRI/ISDN and H.320 signaling models in some places with some additional innovations (if you can call them that) thrown in. H.450.1 - The H.45o series defines Supplementary Services for H.323, namely Call Transfer and Call Diversion. The H.450.1 protocol deals with the procedures and signalling protocol between H.323 entities for the control of supplementary services. This signalling protocol is common to all H.323 supplementary services. The protocol is derived from the generic functional protocol specified in ISO/IEC 11582 for Private Integrated Services Networks (PISN). The H.450 protocol is used to exchange signalling information to control supplementary services over a LAN. It works together with the H.225 protocol. This protocol has no header as all messages are in text, in ASN.1 format. H.450.2 - This is a Call Transfer supplementary service for H.323. The H.450.2 protocol describes the procedures and signalling protocol for the call transfer supplementary service in H.323 networks. This supplementary service allows the served user A to transform an existing call (from user A to B) to a new call between user B and a third user C selected by A. User A may or may not have a call established with the third user prior to the call transfer. This is based on H.450.1 This protocol has no header as all messages are in text, in ASN.1 format. H.450.3 - The H.450.3 is a call diversion supplementary service for H.323. It describes the procedures and signalling protocol for the call diversion supplementary service in H.323 networks. This includes the services Call Forwarding Unconditional (SS-CFU), Call Forwarding Busy (SS-CFB), Call Forwarding No Reply (SS-CFNR) and Call Deflection (SS-CD). These are all supplementary services, which apply during call establishment, providing a diversion of an incoming call to another destination endpoint. This is based on H.450.1 This protocol has no header as all messages are in text, in ASN.1 format. H.264 - H.264 flavor of MPEG-4 (also known as MPEG-4 Part 10 or Advanced Video Coding). This feature is strategically significant because H.264/AVC has been chosen to be part of the next-generation Blu-Ray and HD-DVD blue-laser optical-disc specifications.

Hibernate - an open source Java persistence framework project. HIC - Health Insurance Claim hidden flag - n. [scientific computation] An extra option added to a routine without changing the calling sequence. For example, instead of adding an explicit input variable to instruct a routine to give extra diagnostic output, the programmer might just add a test for some otherwise meaningless feature of the existing inputs, such as a negative mass. The use of hidden flags can make a program very hard to debug and understand, but is all too common wherever programs are hacked on in a hurry.

HyperTransport LOST - Everyone is using PCIe. The current (8/2001) HyperTransport spec calls for an aggregate bandwidth of 6.4 GB per second in a 16-bit configuration, and 12.8 Gb/sec in a 32-bit configuration. In contrast, 32-bit PCI starts at less than 133 MB/second, and scales to only 533 MB/sec at 64-bit configurations HyperTransport is 24 times faster than PCI, out of the gate. HyperTransport is software compatible with PCI - vendors will not have to rewrite their PCI device drivers. Hypothesis Testing - Hypothesis testing refers to the process of using statistical analysis to determine if the observed differences between two or more samples are due to random chance (as stated in the null hypothesis) or to true differences in the samples (as stated in the alternate hypothesis). A null hypothesis (H0) is a stated assumption that there is no difference in parameters (mean, variance, DPMO) for two or more populations. The alternate hypothesis (Ha) is a statement that the observed difference or relationship between two populations is real and not the result of chance or an error in sampling. Hypothesis testing is the process of using a variety of statistical tools to analyze data and, ultimately, to accept or reject the null hypothesis. From a practical point of view, finding statistical evidence that the null hypothesis is false allows you to reject the null hypothesis and accept the alternate hypothesis.

ICAP is, in essence, a lightweight protocol for executing a "remote procedure call" on HTTP messages. It allows ICAP clients to pass HTTP messages to ICAP servers for some sort of transformation or other processing ("adaptation"). The server executes its transformation service on messages and sends back responses to the client, usually with modified messages. Typically, the adapted messages are either HTTP requests or HTTP responses.

ICF - Internet Connection Firewall - Microsoft has recognized the importance of personal firewalls too. Window XP and Windows Server 2003 come with a rudimentary firewall called Internet Connection Firewall. ICF isn't a very useful firewall, although users running it are better off than users without it. The upcoming Windows XP Service Pack 2 will upgrade ICF and rename it "Windows Firewall." PC Magazine recently took a good hard look at it. Windows Firewall won't have all the features of third-party personal firewalls—for instance, it won't have tight control over programs on your system making outbound communications—but it will be turned on by default and will offer much more control over the security of your system than exists today in Windows out of the box.

Systems Integration - Wikipedi Integration Patterns (Book) - Microsoft Integration Testing - testing of combined parts of an application to determine if they function together correctly. The 'parts' can be code modules, individual applications, client and server applications on a network, etc. This type of testing is especially relevant to client/server and distributed systems. Testing conducted after unit and feature testing. The intent is to expose faults in the interactions between software modules and functions. Either top-down or bottom-up approaches can be used. A bottom-up method is preferred, since it leads to earlier unit testing (step-level integration) This method is contrary to the big-band approach where all source modules are combined and tested in one step. The big-band approach to integration should be discouraged. Intel-VT - Intel Virtualization Technology (for CPUs). More info Interface - An abstract class providing a set of methods for a specific service. For example, the IDisplay interface provides a set of methods for basic display services. Each interface has a unique class identifier (AEECLSID), and the name of each interface begins with the letter “I.” In BREW, all the interfaces are derived from a base level class interface called IBase. IBase consists of two standard methods for incrementing and decrementing the reference count of an object. This reference count mechanism allows an object to be shared by multiple users. Interface Tests - Programs that probide test facilities for external interfaces and function calls. Simulation is often used to test external interfaces that currently may not be available for testing or are difficult to control. For example, hardware resources such as hard disks and memory may be difficult to control. Therefore, simulation can provide the characteristics or behaviors for specific function. interlaced - not all vertical lines of the video picture are displayed at once. Usually half the lines are displayed at a time, and all lines are displayed 30 times a minutes (standard TV).

Historically, a mainframe is associated with centralized rather than distributed computing. Today, IBM refers to its larger processors as "large servers" and emphasizes that they can be used to serve distributed users and smaller server (often mid-frames or microprocessor machines) in a computing network. Modern desktop machines have far more power than early mainframes. However, the mainframe manufacturers have kept pace to produce machines that do jobs their smaller brethren could never accomplish. Mainframes still house 90% of the data major businesses rely on for mission-critical applications. This is because mainframes have superior performance, reliability, scalability, and security compared to microprocessors. Maintenance Testing - testing a released system that has been changed.

(5 bits) Encodes the macroblock address predictor (i.e., the last MBA encoded in the previous packet). This predictor ranges from 0-32 (to predict the valid MBAs 1-33), but because the bit stream cannot be fragmented between a GOB header and MB 1, the predictor at the start of the packet can never be 0. Therefore, the range is 1-32, which is biased by -1 to fit in 5 bits. Set to 0 if the packet begins with a GOB header.

MFTE => frame => physical address translation - fast and easy - one per physical page MG - Media Gateway MGC - Media Gateway Controller MGCF - Media Gateway Control Function MGCP - The Media Gateway Control Protocol, developed by Telcordia and Level 3 Communications, is one of a few proposed control and signal standards to compete with the older H.323 standard for the conversion of audio signals carried on telephone circuits (PSTN ) to data packets carried over the Internet or other packet networks. The reason new standards are being developed is because of the growing popularity of Voice over IP (VoIP ). Regular phones are relatively inexpensive because they don't need to be complex; they are fixed to a specific switch at a central switching location. IP phones and devices, on the other hand, are not fixed to a specific switch, so they must contain processors that enable them to function and be intelligent on their own, independent from a central switching location. This makes the terminal (phone or device) more complex, and therefore, more expensive. The MGCP is meant to simplify standards for this new technology by eliminating the need for complex, processor-intense IP telephony devices, thus simplifying and lowering the cost of these terminals. I can say that Megaco is more closely coupled with media applications than MGCP because the base protocol includes semantics for conferencing. Because of that, MGCP may be a better base for non-media-centric applications, such as MPLS-based session control. JAINTM MGCP 1.0 Specification - Final Release Bellcore ( and Level 3 Communications Inc. ( have merged two protocols intended to bridge the gap between circuit-switched and Internet protocol (IP) networks. The resulting protocol is known as Media Gateway Control Protocol, or MGCP, and is a combination of Internet Protocol Device Control (IPDC) and Simple Gateway Control Protocol (SGCP). MGCP enables external control and management of data communication devices, or "media gateways," at the edge of multiservice packet networks by software programs, also known as "call agents" or "media gateway controllers." Media gateways can be voice over IP gateways, voice over asynchronous transfer mode (ATM) gateways, modem banks, cable modems and set-top boxes, soft private branch exchanges (PBXs) and/or cross-connects. Merging IPDC and SGCP (into MGCP) means equipment providers can design to a single spec, so interoperability among a wider range of equipment is possible. But he says that neither SIP nor H.323 were designed to deal with the legacy switched telephone network; whereas MGCP-compliant controllers and gateways will interoperate seamlessly with H.323 and SIP endpoints, as well as with legacy telephones. MGCP Documentation MGCP was originally SGCP, prodcued by Bell and Alcatrel ? MGCP (originally SGCP) was designed to allow Media Gateway Controllers (MGC) to control the Media Gateway (MG) - in effect controlling a switching fabric both on the IP and the TDM domains. MGCP was also found useful with vendors who wanted to simplify Gateways by focusing on either Hardware or Software, but also created political havoc with many major players in the field. At some point in '98 there were no less then 5-candidate protocols all trying to solve the same problem as SGCP/MGCP.

MMS allows mobile phone users to incorporate audio, images, and other rich content with traditional text messages, transforming them into personal collages of vision and sound. Multimedia messaging reshapes the landscape of mobile communication, making it more personal, more versatile, and more expressive than ever before. MMS (Multimedia Messaging Service) is a universally accepted standard that lets users of MMS supportive mobile phones send and receive messages with formatted text, graphics, photo-graphic imagery and audio and video clips. Video sequences, audio clips and high-quality images can be downloaded to the phone from WAP sites, transferred to the phone via an attached accessory, such as a digital camera, or received in an MMS message. MMS messages can be sent either to another MMS-enabled mobile phone or to an e-mail address. Photos, sound and video clips can also be stored in the phone for later use. MMS supports standard image formats such as GIF and JPEG, video formats such as MPEG 4 and audio formats such as MP3 and MIDI. Multimedia messaging is dependent on high transmission speeds, something GPRS and the new high speed 3G technologies can provide. To support the MMS technology, existing GSM networks need an MMS-C (Multimedia Messaging Service Centre).

Modal often describes a secondary window that restricts a user's interaction with other windows. mode - The value or item occurring most frequently in a series of observations or statistical data. The most often occurring value in the data set. A data set may contain more than one mode, e.g., if there are exactly 2 values or items that appear in the data the same number of times, we say the data set is bi-modal. mode bit - n. [common] A flag, usually in hardware, that selects between two (usually quite different) modes of operation. The connotations are different from flag bit in that mode bits are mainly written during a boot or set-up phase, are seldom explicitly read, and seldom change over the lifetime of an ordinary program. The classic example was the EBCDIC-vs.-ASCII bit (#12) of the Program Status Word of the IBM 360. Module - In the BREW model, a library or dynamically loaded code block that exposes one or more interfaces.

This includes procedures and protocols for the distribution of labels between routers, encapsulations and multicast considerations. The initial goals of the working group have been largely completed. In particular, it has produced a number of RFCs that define the base Label Distribution Protocol (LDP), the basic MPLS architecture and encapsulations, and definitions for how MPLS runs over ATM and Frame Relay links.

These are used when the locations of lookup services are unknown. There are 5 publc methods. multicast request protocol - The multicast request protocol is used by clients and services to discover lookup services and is based on UDP multicast. Multi-Domain support on SunFire 3800/4800/6800/E12k/E15k class machines (SUN) multimode - a fiber-optic cabling specification that allows as much as 500 m between devices. Multiple regression - Multiple regression is a method of determining the relationship between a continuous process output (Y) and several factors (Xs). multiported storage subsystems - have more than one SAN connection port (network interface) to support the needs of multiple servers. Multitasking - The ability for the operating system to perform multiple operations at once. Windows NT Workstation is a multitasking operating system which can perform multiple I/O requests at once. SCSI and a Caching RAID coprocessor take advantage of multitasking. MUTEX - Mutual Exclusion variables - Mutual Exclusion Lock mutex object - In interprocess communication, a synchronization object which has a signaled state when the mutex is not owned by a thread, and has a non-signaled state when it is owned. Only one thread at a time can own a mutex. MUTT - A Linux eMail program ;; similar to a patch MUX / Mux - Multiplexer. a device that selects one of several analog or digital input signals and forwards the selected input into a single line. Multiplexer - Wikipedia MV - Mirror View MVA - The conventional multi-domain vertical alignment (MVA) technology has smaller viewing angle in the azimuth angle of 45 degree. MVC - Model-View Controller architecture (from Smalltalk-80) is a good example to use for Visual C++. It separates the application into three parts: 1) Model refers to the application layer, where all application-dependent objects reside. For example, in a drawing program, this is the layer that maintains the graphics objects. 2) View refers to the presentation layer, which presents that application's data to the user. 3) Controller refers to the interaction layer, which provides the interface between the input devices (keyboard, mouse,...) and the View and Model layers. Also used in Java and now ASP.NET MVC - Model View Controller.

Also called: NA N/E - Not Executable N-Tier Application Architecture - N-tier application architecture provides a model for developers to create a flexible and reusable application. By breaking up an application into tiers, developers only have to modify or add a specific layer, rather than have to rewrite the enitire application over, if they decide to change technologies or scale up. In the term "N-tier," "N" implies any number -- like 2-tier, or 4-tier; basically, any number of distinct tiers used in your architecture. Application architectures are part of Layer 7 of the OSI model. NA - NetApp (Network Appliance).

Allows disk drives to manage their own network communications, it is believed that the file sever can be removed as a potential bottleneck. NAT - NAT (Network Address Translation) is the translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated the inside network and the other is the outside. Typically, a company maps its local inside network addresses to one or more global outside IP addresses and unmaps the global IP addresses on incoming packets back into local IP addresses. This helps ensure security since each outgoing or incoming request must go through a translation process that also offers the opportunity to qualify or authenticate the request or match it to a previous request. NAT also conserves on the number of global IP addresses that a company needs and it lets the company use a single IP address in its communication with the world.

The Windows NT native disk format. Provides an efficient data storage format, and allows a range of security settings to be applied to individual files and directories. How many characters can a filename have? The maximum number of characters you can use for a filename depends on whether the file is on an NTFS partition or a FAT partition. You can have a 256-character filename on an NTFS partition but only an 11-character filename on an FAT partition (i.e., an 8-character filename with a 3-character extension). The version of FAT that comes with Windows NT 4.0 supports 255-character filenames, unless you turn on Win 3.1. VFAT uses 256-character filenames. NTFS filenames are case sensitive (except during searches), whereas FAT filenames do not retain case. NTFS filenames can contain any characters, including spaces and uppercase, except " * : / \ ? < > |. VFAT filenames must start with a letter or number and can contain any characters except / \ : | ? " ^. How many files can I create on the root of a FAT partition? The root of a FAT drive holds only 512 entries. Remember that long filenames use multiple entries. Thus, creating numerous long filenames on the root of a partition uses space quickly. NTLM - NT LAN Manager authentication.

BREW object - Generally, an instance of an entity that embodies both specific data and the functions that manipulate it. object - Specifically in object-oriented programming, an object is an entity that has state, behavior and identity. An object's state consists of its attributes and the attributes' current values. An object's behavior consists of the operations that can be performed on it and the accompanying state changes. An object's identity is what you use to distinguish it from other objects. In contrast, COM objects' behavior is defined by the interfaces it supports. A COM object's state is not explicitly specified, but is implied by its interfaces. A COM object's identity is defined by the ability to use IUnknown::QueryInterface to move between interfaces. object serialization - Serialization lets you store objects and handle them with binary input/output streams. object storage - also: object-based storage "a storage architecture that manages data as objects, as opposed to other storage architectures like file systems which manages data as a file hierarchy and block storage which manages data as blocks within sectors and tracks.

OPC endorses the Viewperf and GLperf benchmarks. Viewperf was created by IBM and OPC provides viewsets for it, which are combinations of tests using specific applications to test OpenGL performance. PTC's CDRS (CDRS-03) is used for modeling and rendering. IBM's Data Explorer (DX-03) is used for visualization. Intergraph's DesignReview (DRV-04) is used for 3-D models. Alias/Wavefront's Advanced Visualizer (AWadvs-01) is used for animation, and Lightscape Technology's Lightscape Visualization System (Light-01) is used for radiosity visualization. Developed by the OPC, the GLperf benchmark measures low-level OpenGL 2-D and 3-D graphics primitives. The results are the raw performance of a system rather than the application performance as provided by the Viewperf benchmarks. Viewperf results are in frames per second, and GLperf results are in primitives per second. See GPC. OPD - Onsite Problem Determination openSUSE - Novell renamed its free Linux OS openSUSE, to differentiate it from Enterprise versions. Click for more information OPES - Open Pluggable Services OpenSSL - Secure Sockets Layer was originally designed and implemented by Netscape in 1995 [Hickman1995]. Since then it has gone through a number of revisions [Freier1996]. It is also adopted by IETF as a standard for transport layer security protocol (TLS) [Dierks1999]. To this day, SSLv2, SSLv3 and TLSv1 are still used and supported by the most current releases of popular browsers. Although SSL is supposed to be layered above TCP, it is implemented as a user level protocol. This works well for delivering web applications for multiple platforms without having to modify the kernel in each case. OpenSSL provides a socket like API for developers. But since it is not a true socket interface, developers are stuck with the added complexity of calling the socket interface in additional to the OpenSSL API.

QA - A.K.A. Quality Assurance. Also known as Software Test. This is the group that performs methodical testing of the products developed by engineering. They make no statement of the quality of the product and no guaranty of finding all the bugs in a product. Their job is to take an independent approach to evaluating the product and open bugs against anything they think is broken or not performing as a reasonable end user might expect.

(3G) QS - Quality Systems QS-9000 - QS-9000 is a quality system standard that focuses on helping automotive suppliers ensure that they are meeting/exceeding automotive customer requirements. As mentioned before, it uses ISO 9000 as a core (document control, corrective action, auditing, etc.), but adds quite a few additional requirements. QS-9000 is now being replaced by a newer related standard called ISO/TS 16949. TS 16949 contains all of ISO 9000, QS-9000, and many European standards. TS is much more process-oriented than QS or ISO. It defines the business as a set of processes with inputs and outputs that need to be defined, controlled, improved/optimized, etc. In my view TS looks like someone who knew QS took Six Sigma/BB training and incorporated many of the SS/BB ideas. QSR - Quality Status Report QT4 - Qt is a cross-platform application and UI framework. Qt 4.0: What's New in Qt 4 Qt (toolkit) - Wikipedia QT Extended - an application platform for Embedded Linux-based mobile computing devices (Wikipedia Links Qtopia - Qt Extended, formerly known as Qtopia QTP - HP's Quick Test Pro. See also QTP Qtrees - A qtree can be an entire volume or a subset of a volume. It is similar to a partition in that you cannot move files into or out of a qtree. There are, however, two differences between a qtree and a partition: A qtree is more flexible than a partition because you can change the size of a qtree at any time. A qtree enables you to apply attributes such as oplocks and security style to a subset of files and directories rather than to an entire volume. Quad Block System - Two frames with 4 blocks running coherently, connected by 2 SCIFI-4's. Quality Assurance - A planned and systematic set of activities to ensure that variances in processes are clearly identified, assessed and improving defined processes for fullfilling the requirements of customers and product or service makers. A planned and systematic pattern of all actions necessary to provide adequate confidence that the product optimally fulfils customer's expectations. A planned and systematic set of activities to ensure that requirements are clearly established and the defined process complies to these requirements. "Work done to ensure that Quality is built into work products, rather than Defects." This is by (a) identifying what "quality" means in context; (b) specifying methods by which its presence can be ensured; and (c) specifying ways in which it can be measured to ensure conformance. DAVE's QA Menu ** Quality Attribute - A property of a work product or goods by which its *Quality* will be judged by some *Stakeholder* or stakeholders. (Also "Quality Factor" or [Gilb] "Quality".) Quality attributes are and should be quantifiable in specifications by the definition of some appropriate and practical scale of measure. Quality Audit - A systematic and independent examination to determine whether quality activities and related results comply with planned the Quality System and all Quality documents are filled out or followed. Quality Control - Also called statistical quality control. The managerial process during which actual process performance is evaluated and actions are taken on unusual performance. It is a process to ensure whether a product meets predefined standards and requisite action taken if the standards are not met. Quality Control measures both products and processes for conformance to quality requirements (including both the specific requirements prescribed by the product specification, and the more general requirements prescribed by Quality Assurance); identifies acceptable limits for significant Quality Attributes; identifies whether products and processes fall within those limits (conform to requirements) or fall outside them (exhibit defects); and reports accordingly. Correction of product failures generally lies outside the ambit of Quality Control; correction of process failures may or may not be included. Quality Gap - It is the difference between the approved standards, criteria or expectations in any process or activity and the real results in such process or activity in accordance with the adopted national and or international standards by any country.

In the United Kingdom, these are better known by their initials RCD, and a combined RCD+MCB (miniature circuit breaker) is known as a RCBO (residual-current circuit breaker with overcurrent protection). In Australia, they are sometimes known as safety switches or an RCD. An earth leakage circuit breaker (ELCB) may be a residual-current device, although an older type of voltage-operated earth leakage circuit breaker also exists." - RCP - Rich Client Platform, a software development platform helping software developers to rapidly build new Java applications RCS - Revision Control System, UNIX RCT - Root Canal Treatment RCT - Randomized Controlled Trial RDA - Recommended Dietary Allowance RDAC - Redundant Disk Array Controller (contains the Multipath Device driver) rdb - resident debugger - (DG/UX) RDBMS - Relational DataBase Management System.

Red Hat - A version of Linux. more on Red Hat Linux Red Route - frequent or critical tasks (priority would be High). Red X - Data indicating characteristics which show a change between good and bad. Also known as a critical X Reengineering - Also called Business Process Quality Management or Process Management. The concept of defining macro and micro processes, assigning ownership, and creating responsibilities of the owners. Reengineering is about achieving dramatic, breakthrough improvements often by the application of new technologies. It is the opposite of Kaizen (many gradual improvements) and reflected a return to Western 'Macho' management ideas. The approach was developed by Hammer and Champy. Reference Testing - A way of deriving expected outcomes by manually validating a set of actual outcomes. A less rigorous alternative to predicting expected outcomes in advance of test execution. [Dorothy Graham, 1999] referential integrity - In database management, a set of rules that preserves the defined relationship between tables when records are entered or deleted. For example, enforcing referential integrity would prevent a record from being added to a related table when no associated record in the primary table exists. Reflection - Reflection lets Java code examine information about the methods and constructors of loaded classes as well as make use of those reflected methods and constructors. registered SCN - a switch function that allows notification to registered nodes if a change occurs to other, specified nodes. Regression - The relationship between the mean value of a random variable and the corresponding values of one or more independent variables. Regression Testing - Testing conducted for the purpose of evaluating whether or not a change to the system (all CM items) has introduced a new failure. Regression testing is often accomplished through the construction, execution and analysis of product and system tests. Some good automated test tools are: WinRunner, Quick Test Professional, SilkTest, Rational Robot. Testing that is performed after making a functional improvement or repair to the program. Its purpose is to determine if the change has regressed other aspects of the program [Glenford J.Myers, 1979] register - register will register all paths to a multi-path I/O enabled physical disk, by default. relational database - A method for organizing filkes in a database that prohibits linking files together. In non-relational systems (hierarchical, network), records in one file point to the location of records in another, such as customers to orders and vendors to purchasing. This links are set up ahead of time in order to provide fast daily processing. In a relational database, relationships between files are created by comparing data, such as account numbers and names. A relational system can take any two or more files and generate a new file from records that meet the matching criteria. In practice, a pure relational query can be very slow. In order to speed up the process, indexes are built and maintained on the key fields used for matching. Sometimes, indexes are created "on the fly" when the data is requested. RELATIONAL TERMS CONVENTIONAL TERMS table or relation file tuple record attribute field Release Candidate - A prelease version, that if it passes testing, will be released. Release Candidates are thought to be bug free, but must still be tested.

LU now can be made accessible to standby host data consistency depends on mirror state when secondary LU removed data on LU may need recovery (mirror data state in sync or consistent) data may be unrecoverable (sync in progress or out of sync) may cause primary LU to be inaccessible if number of secondary LUs below minimum required for primary LU in that event, mirror availability state set to attention repeaters - A device that repeats the input signal, usually to allow the signal to be broadcast to a further distance. Repetition Testing - involves doing the same operation over and over. This could be as simple as starting up and shuting down the program over and over. It could also mean repeately saving and loading data or repeatedly selecting the same operation. You might find a bug after only a couple repetitions or it might take thousans of attempts to reveal a problem.

A protocol defined by RFC 1058 that specifies how routers exchange routing table information. With RIP, routers periodically exchange entire tables. Because this is inefficient, RIP is gradually being replaced by a newer protocol called Open Shortest Path First (OSPF). Routing Information Protocol, maintains a database of network hosts and exchange information about the topology of the network (XNS). RIP - Pronounced rip, acronym for raster image processor. RIPv2 - Why ? Because of the installed base of RIP routers Provides VLSM support, authentication, multicasting, "wire-sharing" by multiple routing domains, tags to flag EGP/BGP routes.

The SACC metric measures not only cooling capacity but also how the unit performs on muggy days or hot and dry days, and even accounts for the effect of heat radiating back into the room from the unit’s vent. SACC is expected to replace the less comprehensive Btu rating as the standard measurement for AC power output, but most air conditioners are still described in terms of Btu, so we considered both stats. We also factored in the energy-efficiency ratio (EER), measured in Btu per watt, and dismissed anything less than a 9.0 out of possible 12.0. This rating isn’t as comprehensive as SACC, so we didn’t concern ourselves too much about the specific numbers as long as an AC reached our minimum efficiency threshold. - WIRECUTTER SACCH - Slow Associated Control Channel SACD - Super Audio CD is a high-rsolution audio format developed by Phillips and Sony.

In this situation, the modern fast- running tape drive is unable to stop the tape instantly. Instead, the drive must decelerate and stop the tape, rewind it a short distance, restart it, position back to the point at which streaming stopped and then resume the operation. If the condition repeats, the resulting back-and-forth tape motion resembles that of shining shoes with a cloth.

SIP (VoIP) - SIP, the Session Initiation Protocol, is a signaling protocol for Internet conferencing, telephony, presence, events notification and instant messaging. SIP Forum SIP was developed around the same time as H.323, but was modeled after HTTP. Over the years many of the features of H.323 were added - in a much better way I have to say, and today it pretty much can do everything H.323 can do and more - the few missing gaps are being fixed as we speak in the IETF. - Session Initiation Protocol. This versatile signaling protocol can help you set up collaborative multimedia conferencing and voice-enabled e-commerce. SIP, like HTTP, is versatile and simple to use. It can set up collaborative multimedia conferencing and voice-enabled e-commerce. SIP is expected to become the norm for VoIP implementations within a couple of years, though today just about all enterprise VoIP vendors would rather keep you locked into their proprietary signaling solutions. The IETF published the first version of SIP, RFC 2543, in 1999 and the most recent version, RFC 3261, June 2002.

Smoke Test - Almost a Sanity Test or Aceptance Test to determine if core functionality works and whether or not the product is solid enough for further testing to take place - the crucial functions work, the finer details are ignored. Often QA will have the developers run the Smoke Test, and QA will not accept the software for testing unless it passed the Smoke Test. Smoke Testing is non-exhaustive Sanity Testing is a cursory testing,it is performed whenever a cursory testing is sufficient to prove the application is functioning according to specifications. Sanity Testing is usually a sub-set of Regression Testing. SMP - Serial Management Protocol (for SAS). SMP - Symmetrical Multiprocessing. Two or more processors connected via a high bandwidth link and managed by an OS where each processor has equal access to I/O devices.

SMPP - Short Message Peer-to-Peer SMS - Short Message Service SMS or Short Message Service has been a booming business for the past 2 years (6/02). After free SMS services, SMS chat and dating, companies are discovering inventive ways to use this technology to communicate faster and better. Recent changes in billing possibilities offered by operators allow of new SMS based business models. Reverse billing gives content providers the possibility to charge end users for receiving SMS messages. This new possibility also offers great ways to use SMS as a micropayment solution. In other words, internet users could use SMS to pay small amounts for services, e.g. access to a research report, or products online. Mobile (CNN) SMS - System Management Server (Microsoft) - System Center Configuration Manager, formerly Systems Management Server (SMS).

SMutil - Storage Management 8.4 Utility SN - sequence number SNA - Systems Network Architecture, introduced by IBM to provide a framework for joining together many mutually incompatible IBM products for distributed processing. SNA - IBM Systems Network Architecture - Wikipedia Introduction to SNA - Yale SNACK - Sequence Number Acknowledgement; used by iSCSI to solicit retransmission of specified packets within a sequence. SNACP - SNA PPP Control Protocol, responsible for configuring, enabling and disabling SNA on both ends of the point-point link (PPP). SNADIS - SNA Server’s SNA Device Interface Specification SnapDrive - SnapDrive software offers a rich set of capabilities to virtualize and enhance storage management for Microsoft Windows environments. It is tightly integrated with Microsoft NTFS, providing a layer of abstraction between application data and physical storage associated with that data. It facilitates creation and management of virtual devices on the filer, and allows the creation and management of snapshots either from the Microsoft MMC or via a command line interface. Storage managed by SnapDrive logically appears to the Windows host as locally attached storage. In reality, the capacity comes from a centrally managed pool of networked storage equipped with enhanced attributes. SnapDrive runs on a Windows 2000 host and complements native NTFS volume management with virtualization capabilities. It allows administrators to easily create virtual disks from pools of storage that can be distributed among several storage appliances. SnapDrive is included at no additional charge with the NetApp Windows Host Attach Kit 1.0. SnapLock - Data Persistence (write-once, non-erasable) - NetApp - More info NetApp SnapMirror - asynchronously transfers volumes or qtrees from a source filer to a destination filer or NearStore. This involves an initial baseline transfer, and then block-level incremental updates thereafter. As a result, SnapMirror works very well in LAN and WAN environments where bandwidth is limited. SnapRestore - will revert a LUN or an entire volume containing LUNs to a previous state in only a few seconds, regardless of size or utilization. Furthermore, the SnapRestore operation takes effect immediately, without requiring a reboot of the filer. When SnapRestoring a single LUN, it must be taken offline or unmapped prior to recovery if the LUN has not been destroyed. Snapshot - Point-in-time copy (a snapshot) - NetApp & Others - More info NetApp Snapshot LU - A phantom logical unit that is associated with a specific SnapView Source LU for the purposes of presenting a specific point in time view of the SnapView Source LU. This logical unit is created via Navisphere (IBM) and appears to connected hosts as a copy of a Source LU. The Snapshot LU is "off-line" to connected hosts until a SnapView Session is started. SnapVault - software builds on the asynchronous, block level incremental transfer technology of SnapMirror by providing archival technology. This allows data to be backed up via Snapshots on a filer and transferred on a scheduled basis to a destination filer or NearStore appliance. These snapshots can be retained on the destination for many weeks or even months allowing recovery operations to occur nearly instantaneously from this destination system to the original filer. SnapView - Instaneous LU frozen view feature - Paul McGrath, Brandon Myers, Rajat Gupta Snap View Cache - The disk storage used to hold the original data from a source LU that has been modified since the start of a SnapView session. This storage is pre-allocated and used exclusively for SnapView purposes. The SnapView Cache can consist of multiple logical units; the logical units are then managed as a pool of space. In Longbow phase 1 for each SP, the SnapView feature allows independent, different sized, SnapView caches to be defined. Snap View Cache LU - A logical unit that is assigned to the SnapView Cache. SnapView Chunk size - Refers to the unit of measure that SnapView cache uses to store and allocate blocks of information. All OCFW IO is done in chunk-sized IOs. The default SnapView chunk size (Phase 2) is 64KB and is user configurable. Snap View Session - A SnapView session starts when a snapshot is taken (not when the snapshot is created via Navisphere) of a source LU. A snapshot can be taken via Navisphere Manager. A SnapView session can be scripted from a host using the admsnap command or the Navisphere CLI. The session can be stopped in a similar manner when the snapshot LU is no longer of any use. There is only one active session on a snapshot LU at any given time. There can be many concurrent active sessions, on different snapshot LUs, bound by the array memory resources allotted to the SnapView feature. SnapView Source LU - A logical unit (LU) is one or more disk modules bound into a single entity. The LU is accessible to connected hosts by a logical unit number (LUN), a hexidecimal number that becomes part of the disk unit device name. A LU becomes known as a SnapView Source LU when the administrator indicates that the data on the LU will be part of a SnapView Session. SNDC - Sub-Network Dependent Convergence SNDCP - Sub-Network Dependent Convergence Protocol (SNDCP): the protocol that maps a network-level protocol, such as IP or X.25, to the underlying logical link control. SNDCP also provides other functions such as compression, segmentation and multiplexing of network-layer messages to a single virtual connection SNIA - Storage Networking Industry Association SNIFF TEST - a Reality Test to determine if the product/idea/venture works sufficently well to merit further testing. More info SNMP - Simple Network Management Protocol, developed by the Internet community to allow diverse network objects to participate in a global network management architecture.

SOAP - Simple Object Access Protocol (UPnP). SOAP is a simple XML based protocol to let applications exchange information over HTTP. SOC - Switch On a Chip SoC - (computer) System on a Chip. See System-on-a-chip for more information socket - An endpoint in network communications. Creates a Channel Table and gets an object pointer. SOCKS - SOCKS Protocol Version 5 This protocol provides a framework for client-server applications in both the TCP and UDP domains to conveniently and securely use the services of a network firewall. The protocol is conceptually a "shim-layer" between the application layer and the transport layer, and as such does not provide network layer gateway services, such as forwarding of ICMP messages. SOCKS Version 4 provides unsecured firewall traversal for TCP-based client-server applications, including TELNET, FTP, and protocols such as HTTP, WAIS and GOPHER. This version of SOCKS extends the SOCKS Version 4 model to include UDP, and extends the framework to include provisions for generalized strong authentication schemes. It also adapts the addressing scheme to encompass domain-name and V6 IP addresses. The implementation of the SOCKS protocol typically involves the recompilation or relinking of TCP-based client applications to use the appropriate encapsulation routines in the SOCKS library. SOD - A separation of duties (SOD)- assessment is an internal control which provides management with reasonable assurance that no one individual has responsibilities or accesses that would allow employees to misuse or divert company assets. SOE - SCSI Command Offload Engine (like TOE for SCSI) SoE - SCSI over Ethernet SOF - Start Of Frame; a field used to deliniate the beginning of a frame. SOFD - Staged Online Firmware Download (IBM) Software development process - A software development process, also known as a software development life-cycle (SDLC), is a structure imposed on the development of a software product. Similar terms include software life cycle and software process. It is often considered a subset of systems development life cycle. There are several models for such processes, Software development process - Wikipedia Software Inspection Software Inspection Plan software-testing methodology - an example: 1] Creating a test strategy 2] Creating a test plan/design 3] Executing tests. soft zoning - is accomplished in switches by reading trasmission frames as they enter the switch and determining whether of not the destination and source addresses in the frame belong to the same zone. If both address are not in the same zone, the frame is discarded with or without an error message, depending on the specific implementation. soft zoning is in contrast to hard zoning. SoIP - Storage over IP. Storage over IP (SoIP) is a concept that combines the features of SANs, which provide high availability and performance, with features of IP networks. This technology provides product compatability, with familar technology and network scalability similar to iSCSI, except that it focuses on the the use of UDP protocols versus TCP/IP. SoIP technology enables traditional storage system interfaces, such as SCSI, Fibre Channel, Fibre Channel Arbitrated Loop, and InfiniBand interfaces, to connect to a standard IP infrastructure. It uses exisiting networking standards, such as OSPF, MPLS and SNMP, along with IP and Gigabit Ethernet. SoIP is a framework for deploying native IP storage solutions. It is designed to support transparent interoperability of storage devices based on Fibre Channel, SCSI and Gigabit Ethernet storage devices. The object is to enable any existing Fibre Channel or SCSI device, such as servers with host bus adapters (HBA) or storage subsystems, to be included in an SoIP storage network without modifcation. SoIP could also be connected to native IP Gigabity Ethernet storage devices by means of devices such as SoIP adapters.

Here’s the breakdown: Voice is your own. It’s a developed way of writing that sets you apart from other writers (hopefully). It’s your personality coming through on the page, by your language use and word choice. When you read a Dave Barry column, you know it’s his. Why? He’s developed a distinct writing voice. Style is much broader than voice. Some writers have a writing style that’s very ornate—long, complex and beautiful sentences, packed with metaphors and imagery (think Frank McCourt and John Irving). Others have a more straightforward style —sparse prose, simple sentences, etc. Here’s one way to think about it: WD tries to have all its articles fit a similar style—conversational yet straightforward. But between the covers, each piece is written by a different author whose own voice colors his particular piece. So the continuity of the magazine stays together, but each piece is still different. SPC - Storage Performance Council. A group comprised of companies predominately in the data storage and server business, formed to develop industry-standard benchmarks for storage networks. SPC-1 - Storage Performance Benchmark 1. Represents a workload that is both throughput and response time sensitive.

SPF - Sender Policy Framework - an anti-spam initiative which verifies email sender domains against IPs to prevents email address forgery, a common spammer technique, is closing in on becoming an RFC. How do I implement SPF. SPI - Stateful Packet Inspection. A simpler, yet more rigorous method of access control is to implement a firewall like a Stateful Packet Inspection Firewall (SPI) that analyzes packets in terms of sessions. How the SPI Firewall works is it will examine all incoming data transmission – if a packet is deemed a legitimate reply to a previous request from within the network, the SPI Firewall would permit its passage through. Otherwise, access is denied. Such an approach allows relatively unrestricted transmission from within the network, and selective but flexible access from the outside. The SPI Firewall also uses a monitoring algorithm to track individual connections and it is also enabled to grant open temporary access in the firewall under appropriate conditions. For example, packets are allowed to pass only if associated with a valid session initiated from within the network. Now being superceded by DPI. Stateful firewall - Wikipedia stateful inspection Stateful Packet Inspection (SPI) Comparing NAT, Static Content Filtering, SPI, and Firewalls - NetGear SPI - Serial Peripheral Interface SPI - SPI = serial flash chip using the SPI bus/interface (basically a FWH with less pins) FWH are SPI are typically thought of as chips (some insist it's a hub).

Examples are: Customers, owners, employees, associates, partners, contrators, suppliers, related people or located near by. Alternative definition: any group or individual who can affect or who is affected by achievement of a firm's objectives. Standard - A definition or that has been approved by a recognized standards organization or is accepted as a by the industry. Standards exist for programming languages, operating systems, data formats, communications protocols, and electrical interfaces. From a user's standpoint, standards are extremely important in the computer industry because they allow the combination of products from different manufacturers to create a customized system. Without standards, only hardware and software from the same company could be used together. In addition, standard user interfaces can make it much easier to learn how to use a new application. DAVE's Standards, MISC. MENU ** DAVE's Standards ORGANIZATIONS Protocols Standard Deviation - A statistic used to measure the variation in a distribution. Sample standard deviation is equal to the square root of (the sum of the squared deviations of the mean divided by the sample size minus 1). Where the whole population is known, the minus 1 "fudge factor" should be omitted.

This is different from a datagram socket, which is connectionless. In the standard I/O context: a stream represents a FILE control block that is open for reading or writing. Stress Testing - The opposite of Load Testing. With stress testing you starve the software; with load testing, you feed the software all it can handle. Running the software under less-than-ideal conditions - low memory, low disk space, slow CPUs, slow modems, and so on. Look at your software and determine what external resources and dependancies that it has. Stress testing is simply limiting the resources to their bare minimum. Your goal is to starve the software.

See bitblt. stripe - A logical storage space comprising a portion (or "strip") of a number of physical didks. A stripe set is the array of stripes that form a striped RAID volume. Striping is generally used because it speeds up disk I/O. Data from stripes is stored and retrieved more uniformly than in the case with concatentation. In other words, data may be retrieved from a number of stripes simultaneously, resulting in a decrease in how much time the I/O operations takes to complete.

Click here for more T-SQL INFORMATION T3 - a serial communications link supporting 45 Mbps T.38 - The T.38 IP-based fax service maps the T.30 fax protocol onto an IP network. Both fax and voiced data are managed through a single gateway. T.38 uses 2 protocols, one for UDP packets and one for TCP packets. Data is encoded using ASN.1 to ensure a standard technique. It allows users to transfer facsimile documents between 2 standard fax terminals over the Internet or other network using IP protocols. H.323 can be used here in the same way that it is used to support Voice over IP. TCP messages The T.38 data (Internet Fax Protocol) is contained in the payload of the TCP or UDP messages. The T.38 packet provides an alert for the start of a message. An ASN.1 Application tag identifies it; if this tag is not present the session is aborted. UDP messages T.38 messages may also be sent over the UDP transport layer. The UDP header is followed by the UDPTL payload which consists of sequence number and a payload. T.120 - shared whiteboard T.125 - The T.120 family of protocols describe protocols and services for multipoint Data Conferencing including multilayer protocols which considerably enhance multimedia, MCU and codec control capabilities, permitting greater MCU operational sophistication beyond that described in H.231 and H.243. T.125 describes the Multipoint Communication Service Protocol (MCS). It defines: Procedures for a single protocol for the transfer of data and control information from one MCS provider to a peer MCS provider. The structure and encoding of the MCS protocol data units used for the transfer of data and control information. Procedures may be: Interactions between 2 parallel MCS providers by exchanging MCS protocol data. Interactions between MCS providers and users by exchanging MCS primitives. Interactions between an MSC provider and a transport service provider by exchanging transport service primitives. The MCS provider communicates with MCS users through a MCSAP (MCS Service Access Point), by means of MCS primitives defined in T.122. MCSPDU (MCS protocol Data unit) exchanges occur between MCS providers that host the same MCS domain. The MCS provider can have multiple peers; each reached directly by a different MCS connection or indirectly through a peer MCS provider. An MCS connection is composed of either one MAP connection or one or more transport connections. The protocol exchanges are preformed using the transport layer using a pair of TSAPs (Transport Service Access Points). The MCS PDU is the MCS protocol data unit. This is the information exchanged in the MCS protocol consisting of control information transferred between MCS providers to coordinate their joint operation and possibly data transferred on behalf of MCS users for whom they provide service. Each MCSPDU is transported as one TSDU (Transport service data unit) across a TC (Transport connection) belonging to an MCS connection. Connect MCSPDUs are unlimited in size. Domain MCSPDUs are limited in size by a parameter of the MCS domain. The structure of Version 2 and Version 3 MCSPDUs is defined in ASN.1 and appears as text or numeric messages.

To change a bit from whatever state it is in to the other state; to change from 1 to 0 or from 0 to 1. This comes from `toggle switches', such as standard light switches, though the word `toggle' actually refers to the mechanism that keeps the switch in the position to which it is flipped rather than to the fact that the switch has two positions. There are four things you can do to a bit: set it (force it to be 1), clear (or zero) it, leave it alone, or toggle it. (Mathematically, one would say that there are four distinct boolean-valued functions of one boolean argument, but saying that is much less fun than talking about toggling bits.) TOI - Transfer Of Information (any NetApp meeting for this purpose) Token Ring - LAN protocol where all stations are connected in a ring and each station can directly hear transmissions only from its immediate neighbor (IBM). tomcat - Tomcat is the reference implementation for Servlets and Java Server Pages (JSP).

These are both useful ways of using XML, but they will not help anyone find the information they are looking for. What changes with the introduction of XML is that the document processes become more controllable and can be automated to a greater degree than before, while applications can now communicate internally and externally. But the big picture, something that collects the key concepts in the organization's information and ties it all together, is nowhere to be found. This is where topic maps come in. With topic maps you create an index of information which resides outside that information topology - the physical or logical arrangement of devices in a networked configuration ToS - Type Of Service, this field in the IP packet header that was intended to provide a hint of the preferred routing policy or packet-routing preference. routing protocols that are ToS-capable are able to make routing decisions based in bits in the ToS Field of the IP Header.

The integration of TTCN and ASN.1 means that there are powerful constructs for describing data as well as behaviour. Originally intended as a generic notation for specifying conformance tests of OSI protocols TTCN has been widely embraced by the telecommunications industry and other industrial users. ETSI has been an extensive user of TTCN since 1992. The language allows the specification of complex tests in a manner that is independent of the test systems which will eventually execute them, making it an ideal language for standardised test suites.

It is intended for use only with ISPs and online services that are digitally attached to the telephone system. Most service providers are typically connected with high-speed digital T1 or T3 circuits. In practice, the downstream link isn't generally faster than 45 Kbps in these PCM modems, so called because they use pulse code modulation downstream and standard V.34 upstream. Initially, two incompatible technologies competed in this arena: x2 from U.S. Robotics and K56Flex from Rockwell and Lucent. Such modems can be upgraded to V.90 if they contain software-upgradable memory chips. See V.92, V.34 and channel bonding. V.92 - An improved version of the V.90 modem that boosts the upstream rate from 33.6 Kbps to 48 Kbps. Introduced in 2000, V.92 reduces connection time (handshaking) by remembering the previous settings negotiated when dialing the same telephone number. It also supports call waiting by allowing the data session to be put on hold while a voice call is taken. See V.90.

"A viewpoint can be thought of as a combination of the idea of an “actor”, "Knowledge source”, “role” or “agent” in the development process and the idea of a “view” or “perspective” which an actor maintains." It is often used to choose the proper view of the entire project for a particular Actor. In database theory, a view consists of a stored[clarify] query accessible as a virtua table in a relational database or a set of documents in a document-oriented database composed of the result set of a query or map-and-reduce functions. Unlike ordinary tables (base tables) in a relational database, a view does not form part of the physical schema: it is a dynamic, virtual table computed or collated from data in the database. Changing the data in a table alters the data shown in subsequent invocations of the view. In some NoSQL databases views are the only way to query data.

Webinar - Online Seminar Weblogic - from Oracle (BEA) - application server - application infrastructure for developing, integrating, securing, and managing distributed Java applications. WebLogic Suite | Oracle Weblogs - A Weblog allows you to easily publish a wide variety of content to the Web. You can publish written essays, annotated links, documents (Word, PDF, and PowerPoint files), graphics, and multimedia. You don't have to be a programmer. A weblog is, literally, a 'log' of the web - a diary-style site, in which the author (a weblogger, or 'blogger') links to other web pages he or she finds interesting. A weblog is personal -- it's done by a person, not an organization. Web Services - Looking back over the last six years, it is hard to imagine networked computing without the Web. The reason why the Web succeeded where earlier hypertext schemes failed can be traced to a couple of basic factors: simplicity and ubiquity. From a service provider's (e.g. an e-shop) point of view, if they can set up a web site they can join the global community. From a client's point of view, if you can type, you can access services. From a service API point of view, the majority of the web's work is done by 3 methods (GET, POST, and PUT) and a simple markup language. The web services movement is about the fact that the advantages of the Web as a platform apply not only to information but to services. By "services", I don't mean monolithic coarse-grained services like, but, rather, component services that others might use to build bigger services. Microsoft's Passport, for instance, offers an authentication function exported on the Web. So hypothetically, an electronic newspaper like the Washington Post can avoid creating its own user authentication service, delegating it to Passport.

Zombie process - Wikipedia Zombie processes can only occur in Unix or Unix-like operating systems. See also LINUX / UNIX Info zones - access zones - usually created by SAN switching to provide virtual networks to prevent some ports from accessing other ports. One purpose might be to limit some storage devices so that normally only Host 'C' can see them. Hubs do not provide zoning, as rings and their associated hubs do not have a natural mechanism to process frames (and thus get address or port number information). zone transfer - The process of copying an authoritative DNS name server's database of hostnames and IP addresses belonging to a contiguous section of a domain to a secondary name server. zoning - a function provided by fabric switches or hubs that allows segregation of nodes by physical port, name or address. FICON devices do not use the Fibre Channel name server, therefore name server-based zoning does not affect FICON connectivity. However, the name server does affect distribution of registered state change notification (RSCN) service requests to FICON devices. If a FICON device is not in the same zone as other devices, state changes are not properly communicated. All FICON devices must be included in the same zone to facilitate proper state change notification. Regardless of the director or switch operating mode, FCP devices must be zoned in the traditional fashion, and FICON devices must be zoned to provide isolation from the FCP devices. ****
