LAN Emulation Redundancy   

LAN Emulation 
Overview

LAN Emulation

 (LANE) is a method of connecting LAN users over an ATM 

network that enables them to communicate with each other as if they 
were operating over traditional LANs. You can configure LANE in a ATM 
network in several ways:

To connect legacy end stations directly to other legacy systems, as well 
as to servers, routers, switches, and other networking devices that are 
attached to the ATM network. 

To connect bridged-LAN environments to each other over ATM. In this 
case, the emulated LAN acts as a bridge on the ATM network.

To connect ATM end stations to each other, enabling communication 
between them.

More than one emulated LAN can operate on the same ATM network. 
However, each of the emulated LANs is independent of the others and 
users cannot communicate directly across emulated LAN boundaries.
