Avaya C460 Reference Guide
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 
inform the bridges of the topology of the network and detect loops and topology 
changes.
Broadcasting
A common method of information transmission in which a packet is sent to every 
port on the network. 
Bridge
A device connecting two networks using similar protocols. A bridge filters and 
forwards data between the networks according to their destination addresses.
Burst
A transmission of data at a faster rate than normal. Data bursts can be carried out in 
several ways. A burst is always limited in time and can take place only under 
special conditions.
Bus
A transmission path or channel. A bus is typically an electrical connection with one 
or more conductors, where all attached devices receive all transmissions at the same 
time.
