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,
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
