Avaya M-ACCF/SF manual Address Resolution, Connection Management

Chapter 1 Overview

Address Resolution

Address resolution is the procedure by which a LEC associates a LAN destination with the ATM address of another LEC or the BUS. Address resolution allows clients to set up data direct VCCs to carry frames (refer to Figure 1.5).

Figure 1.5 Address Resolution

Connection Management

In Switched Virtual Connection (SVC) environments, the LAN Emulation entities (LEC, LES and BUS) set up connections between each other using UNI signaling.

LAN Emulation Components in Your Network

Each Emulated LAN consists of a single LANE Service, and a number of LAN Emulation clients.

A LANE Service consists of:

•A LAN Emulation Server (LES)

•A Broadcast and Unknown Server (BUS)

•Optional LAN Emulation Configuration Server (LECS).

Figure 1.6 shows a logical view of a typical ELAN.
