This high speed transport technology, developed by Hewlett Packard, can be made to operate on existing 1. Base. T Ethernet networks. Based on the IEEE 8. B5. B local fiber. Mbps over multimode fiber. See also TAXI 4. B5. B. 0. 81. 0B local fiber. Fiber channel physical media that supports speeds up to 1. Mbps over multimode fiber. A B bit signaling. Procedure used in T1 transmission facilities in which each of the 2. T1 subchannels devotes one bit of every sixth frame to the carrying of supervisory signaling information. Also called 2. 4th channel signaling. AALATM adaptation layer. Service dependent sublayer of the data link layer. The AAL accepts data from different applications and presents it to the ATM layer in the form of 4. ATM payload segments. AALs consist of two sublayers, CS and SAR, AALs differ on the basis of the source destination timing used, whether they use DBR or VBR, and whether they are used for connection oriented or connectionless mode data transfer. At present, the four types of AAL recommended by the ITU T are AAL1, AAL2, AAL34, and AAL5. AAL1. ATM adaptation layer 1. One of four AALs recommended by the ITU T. AAL1 is used for connection oriented, delay sensitive services requiring constant bit rates, such as uncompressed video and other isochronous traffic. AAL2. ATM adaptation layer 2. One of four AALs recommended by the ITU T. AAL2 is used for connection oriented services that support a variable bit rate, such as some isochronous video and voice traffic. AAL34. ATM adaptation layer 34. One of four AALs merger from two initially distinct adaptation layers recommended by the ITU T. AAL 34 supports both connectionless and connection oriented links, but is primarily used for the transmission of SMDS packets over ATM networks. AAL5. ATM adaptation layer 5. One of four AALs recommended by the ITU T. AAL5 supports connection oriented, VBR services, and is used predominantly for the transfer of classic IP over ATM and LANE traffic. AAL5 uses SEAL and is the least complex of the current AAL recommendations. It offers low bandwidth over head and simpler processing requirements in exchange for reduced bandwidth capacity and error recovery capability. AARPApple. Talk Address Resolution Protocol. Protocol in the Apple. Talk protocol stack that maps a data link address to a network address. AARP probe packets. Packets transmitted by AARP that determine whether a randomly selected node ID is being used by another node in a nonextended Apple. Talk network. If the node ID is not being used, the sending node uses that node ID. If the node ID is being used, the sending node chooses a different ID and sends more AARP probe packets. ABMAsynchronous Balanced Mode. An HDLC and derivative protocol communication mode supporting peer oriented, point to point communications between two stations, where either station can initiate transmission. ABR1. available bit rate. QOS class defined by the ATM Forum for ATM networks. ABR is used for connections that do not require timing relationships between source and destination. ABR provides no guarantees in terms of cell loss or delays, providing only best effort service. Traffic sources adjust their transmission rate in response to information they receive describing the statue of the network and its capability to successfully deliver data. Compare with CBR, UBR, and VBR. Router located on the border of one or more OSPF areas that connects those areas to the backbone network. ABRs are considered members of both the OSPF backbone and the attached areas. They therefore maintain routing tables describing both the backbone topology and the topology of the other areas. ACAlternating Current. An electrical power transmission system in which the direction of current flow alternates on a periodic basis. Accelerator. A hardware addition to an existing computing device that increases the computers processing speed and capabilities. Access. Referring to the ability of a computing device to use data or resources beyond its native capabilities. Access List. List kept by routers to control access to or from the router for a number of services. For example, the list can prevent packets with a certain IP address from leaving a particular interface on the router. Access Method. The type of Media Access Control method that a node uses to gain control of a network. Accounting. One of five categories of network management defined by ISO for. 8Mm Mauser Serial Numbers. Managementmanagement of OSI networks. Accounting management subsystems are responsible for collecting network data relating to resource usage. See also configuration management, fault management, performance management, and security management. Accuracy. Referring to how closely a test instruments measurements compare to a standard value, usually expressed as a percentage of the value measured.
