PortMaster Configuration Guide
baud
The number of discrete signal events per second occurring on a communications channel. 
Although not technically accurate, baud is commonly used to mean bit rate.
B channel
Bearer channel. A 64Kbps synchronous channel that is part of an ISDN Basic Rate 
Interface (BRI).
BGP
Border Gateway Protocol. A routing protocol for exchanging network reachability 
information among autonomous systems. A routing device can use this information to 
construct a “map” of autonomous system connectivity. Version 4 of this protocol (BGP-4), 
which supports classless interdomain routing (CIDR) and route aggregation, is the 
predominant routing protocol used to propagate routes between autonomous systems on 
the Internet. BGP uses TCP as its transport protocol. 
BGP-4
Version 4 of BGP. See also BGP.
BONDING
Bandwidth on Demand Interoperability Group. A method for combining two B channels 
into a single 128Kbps channel.
booting
The process in which a device obtains information and begins to process it to attain a state 
of normal operation.
BOOTP
Bootstrap Protocol. A protocol based on UDP and IP that enables a booting host to 
dynamically configure itself without user supervision. BOOTP provides a way for a host 
on a network to acquire its assigned IP address, the IP address of a boot server host, and a 
file to load into memory and run.
