Term Definition
Backplane The main BUS that carries information in the device.
Bandwidth
Specifies the amount of data that can be transmitted in a fixed amount of time. For digital
devices, bandwidth is defined in Bits per Second (bps) or Bytes per Second.
Bandwidth Assignment Indicates the amount of bandwidth assigned to a specific application, user, and/or interface.
Baud Indicates the number of signaling elements transmitted each second.
Best Effort Indicates that traffic is assigned to the lowest priority queue, and packet delivery is not guaranteed.
BGP
Border Gateway Protocol. Enables information sharing, routing information between
groups of routers.
Boot Version Indicates the boot version.
BootP
Bootstrap Protocol. Enables a workstation to discover its IP address, an IP address of a
BootP server on a network, or a configuration file loaded into the boot of a device.
BPDU
Bridge Protocol Data Unit. Provide bridging information in a message format. BPDUs
are sent across switch information with in Spanning Tree configuration. BPDU packets
contain information on ports, addresses, priorities, and forwarding costs.
Bridge
A device that connects two networks. Bridges are hardware-specific, however they are
protocol-independent. Bridges operate at Layer 1 and Layer 2 levels.
Broadcast Domain
Device sets that receive broadcast frames originating from any device within a designated
set. Routers bind broadcast domains, because routers do not forward broadcast frames.
Broadcast Storm
An excessive amount of broadcast messages simultaneously transmitted across a
network by a single port. Forwarded message responses are heaped onto the network,
overloading network resources or causing the network to time out.
Broadcasting A method of transmitting packets to all ports on a network.
Burst
A packet transmission at faster than normal rates. Bursts are limited in time and only
occur under specific conditions.
Burst Size Indicates the burst size transmitted at a faster than normal rate.
C
CBS
Committed Burst Size. Indicates the maximum number of data bits transmitted within a
specific time interval.
CDB Configuration Data Base. A file containing a device’s configuration information.
CIDR
Classless Interdomain Routing. Based on route aggregation. Routers group routes
together, and reduce the amount of routing information carried by the core routers.
Several IP networks appear to networks outside the group as a single, larger entity.
CIR
Committed Information Rate. Indicates the rate (Bps) that data is transmitted using frame
relay services (FRS). The rate is averaged over a minimum time increment.
Class Map
An aspect of Quality of Service system that is comprised of an IP ACL and/or a MAC
ACL. Class maps are configured to match packet criteria, and are matched to packets in
a first-fit fashion.
Class of Service
Class of Service (CoS). The 802.1p priority scheme. CoS provides a method for tagging
packets with priority information. A CoS value between 0-7 is added to the Layer II header
of packets, where zero is the lowest priority and seven is the highest.
Classless Inter-Domain
Routing
Creates new addresses on the internet. The new addresses are distributed to ISPs for
their customers’ use. CIDR reduces the Internet routers’ burden by combining routes.
One IP address represents thousands of addresses serviced by a major backbone
provider.
