ARP
Address Resolution Protocol. The Internet protocol used to dynamically bind
the low-level, physical, hardware network address to the high-level IP address
for a given device. ARP is defined in RFC 826 and limited to physical
network systems that support broadcast packets to all devices on the network.
ARP table A cache table that contains MAC-address-to-IP-address mapping information.
authentication Often used with encryption, authentication can be enabled or disabled on a per
serial interface basis. Like a password, it is used by both ends of a serial
interface to tell the other who it is, and to verify the receiver claims to be.
When this feature is enabled, every packet will contain the encrypted
authentication key, and any packet that fails the authentication will be
dropped.
B channel
Bearer channel. Part of an ISDN interface able to carry voice or data over an
ISDN network at 64 Kb/s.
bandwidth Bandwidth is a measure of the capacity of a network connection or device to
carry data. The amount of data that is transmitted in a fixed amount of time
depends on the bandwidth capacity of the connection.
BootP
Boot Protocol. A protocol that allows a diskless workstation to boot and
obtain necessary information, such as an IP address.
BootP Relay Agent
A router that forwards BootP requests to BootP servers that do not reside on
the same network.
bridge A device that links two or more local area networks, monitors packets on the
connected networks, and forwards only packets destined for the other
network. Bridges function at the data link layer (MAC layer) of the OSI
reference model and selectively filter or forward traffic, based on the
destination address of the frame.
bridge address table
A table containing mapping between MAC addresses and interfaces in a
bridge.
