ASBR

See “Autonomous System Boundary Router” on page 3.

Autonomous System Boundary Router

ABR located between an OSPF autonomous system and a non-OSPF network. ASBRs run both OSPF and another routing protocol, such as RIP. ASBRs must reside in a non-stub OSPF area. See also ABR, non-stub area, and OSPF. (Cisco Systems Inc.)

Auto-negotiation

A feature that allows twisted-pair ports to advertise their capabilities for speed, duplex and flow control. When connected to a port that also supports auto-negotiation, the link can automatically configure itself to the optimum setup.

Auto Uplink

Auto UplinkTM technology (also called MDI/MDIX) eliminates the need to worry about crossover vs. straight-through Ethernet cables. Auto UplinkTM will accommodate either type of cable to make the right connection.

AVL tree

Binary tree having the property that for any node in the tree, the difference in height between the left and right subtrees of that node is no more than 1.

B

BPDU

See “Bridge Protocol Data Unit” on page 4.

Backbone

The part of a network used as a primary path for transporting traffic between network segments.

Bandwidth

The information capacity, measured in bits per second, that a channel could transmit. Bandwidth examples include 10 Mbps for Ethernet, 100 Mbps for Fast Ethernet, and 1000 Mbps (I Gbps) for Gigabit Ethernet.

Baud

The signaling rate of a line, that is, the number of transitions (voltage or frequency changes) made per second. Also known as line speed.

BootP

See “Bootstrap Protocol” on page 4.
