Glossary

a significant event has occurred on the network.

ARP

Address Resolution Protocol. A TCP/IP protocol used to convert an IP address into a physical address, such as an Ethernet address. The sender broadcasts an ARP request onto the TCP/IP network. The host whose IP address matches the requested address then replies with its physical hardware address.

ATM

Asynchronous Transfer Mode. ATM is an international standard for cell relay in which multiple service types such as voice, video, or data are conveyed in fixed- length (53-byte) cells. The constant and relatively small cell size allows ATM equipment to transmit video, audio, and computer data over the same network with an efficient allocation of network resources. Constant cell size also allows cell processing to occur in hardware. This reduces transit delays.

Backbone

Ahigh-bandwidth connection between switches. A backbone link normally operates in Full Duplex Mode, sending packets in both directions simultaneously.

Beacon Frame

Refer to Beaconing.

Beaconing

An error detection mechanism in Token Ring networks. When a station detects a serious network problem, it sends a Beacon Frame. The Beacon Frame defines a failure domain that includes the station reporting the failure, its nearest active upstream neighbor, and everything in between. Beaconing initiates a process in which the nodes in the failure domain perform diagnostics and attempt to reconfigure the network around the failed areas.

BGP

Border Gateway Protocol. An Internet protocol that enables groups of routers to share routing information so that efficient, loop-free routes can be established.

BOOTP

Bootstrap Protocol. An Internet protocol that enables a diskless workstation to discover its own IP address, the IP address of a BOOTP server on the network, and a file to be loaded into memory to boot the machine. This enables the workstation to boot without a hard or floppy disk drive.

BPDU

Bridge Protocol Data Unit. A packet that is transmitted at configurable intervals to exchange information among bridges in the network. Among other things, BPDUs
