GFC

Generic Flow Control — A 4-bit field in the ATM cell header in order to support multiplexing functions. Its default value is ‘0000’, when the GFC protocol is not enforced. The GFC mechanism is intended to support simple flow control in ATM connections.

HEC

Header Error Control or Header Error Check — A

1-byte field in the cell header used for the header error detection and correction. Due to the importance of the information contained in the header, HEC is a useful and important field.

ILMI

Interim Local Management Interface — Published by the ATM Forum, this standard provides extra diagnostic, monitoring and configuration services at the User-to-Network Interface (UNI). It uses the Simple Network Management Protocol (SNMP) and a MIB.

LAN Emulation (LANE)

A technique that specifies the interfaces and protocols needed for providing LAN-supported functionality and connectivity in an ATM Environment. LANE allows existing LAN protocols to interoperable with the ATM protocols, interfaces and devices.

LE_ARP

LAN Emulation Address Resolution Protocol — The ARP used in LAN Emulation for binding a requested ATM address to the MAC address.

GLOSSARY 3

LEC

LAN Emulation Client — Typically located in an ATM end-system (for example, an ATM Module or ATM Switch), its task is to maintain address resolution tables and to forward data traffic. It is uniquely associated with an ATM address.

LECS

LAN Emulation Configuration Server — A server whose main function is to provide configuration information to a LEC (such as the ELAN it belongs to or its LES).

LES

LAN Emulation Server — A server that provides support for the LAN Emulation address resolution protocol (LE_ARP). The LECs register their own ATM and MAC addresses with the LES. A LES is uniquely identified by an ATM address.

link

Physical connection between two nodes in a network. It can consist of a data communication circuit or a direct channel (cable) connection.

MIB

Management Information Base — A data structure that defines objects for referencing variables such as integers and strings. In general, it contains information regarding a network’s management and performance, for example, traffic parameters.
