List of terms

gateway

1See accounting gateway (page 6).

2See DPN gateway (page 43).

3See external gateway (EG) (page 51).

4See FR-ATM gateway (page 56).

5See gateway identifier (GID) (page 58).

6See internal gateway (page 66).

7See X.25 gateway (page 149).

8See X.75 gateway (page 149).

gateway identifier (GID)

An integer that uniquely identifies an X.25 gateway or an X.75 gateway in a network.

GCRA

See generic cell rate algorithm (GCRA) (page 58).

general packet radio service

Apacket-linked technology that enables high-speed, 115-kbit/s, wireless Internet, and other data communications.

general virtual circuit interface (GvcIf)

GvcIf is a networking feature providing circuit establishment between LAN/ WAN services.

generic cell rate algorithm (GCRA)

An algorithm used in a Nortel Multiservice Switch ATM network to monitor and police network traffic. In Multiservice Switch traffic management, GCRA is used by usage parameter control (UPC) to enforce conformance at the source ATM terminal.

generic flow control (GFC)

Afour-bit field in the ATM cell header at a user-to-network interface intended for traffic flow control between the user and network equipment.

generic queue manager (GQM)

A traffic management device (ASIC) which resides on GQM function processor (FP) cards. The GQM descends from other traffic management devices such as the AQM and QRD, and is capable of OC-48. It differs considerable from the other traffic management devices in that it will schedule up to a single OC-48 channel, its scheduling algorithms are frame or cell
