GLOSSARY 3

Cell switching

Network technology that is used for delay-sensitive traffic such as voice and video.

CLP

Cell Loss Priority. The last bit of the fourth byte in an ATM cell header. This bit indicates the cell discard priority. If this bit is set, the network can discard the cell when the network is congested and conditions warrant dropping the cell.

Connectionless ATM

Mode in which the equipment sending the ATM cells adds the destination address to each cell, thus eliminating signaling.

End system

A machine intended for running user application programs and connected to a network. In an ATM network, an ATM connection is terminated or initiated at the end station.

GFC

Generic Flow Control. A cell header field that is used for multiplexing streams of data in an ATM network.

Header

The bits within a cell that are allocated to the control of the cell payload within an ATM network.

HEC

Header Error Control. A cell header CRC field that can be used to correct single-bit errors in the header, and to detect multiple bit errors.

ICMP

Internet Control Message Protocol. A network-layer Internet protocol that enables packets to report errors and other relevant information for packet processing purposes.
