Routing in the X-Switch Domain

The principle behind the Avaya routing evolution is to move routing from the backbone to the edges. This controls the traffic from the moment it enters the LAN and not just after it reaches the backbone.

Figure 2.3 shows how an M-MLS routing module in one of the 2 Avaya M770 Multifunction switches can provide routing for all users on either side of the ATM network. The Avaya M770 is connected to the ATM cloud via the M-ACC ATM Access Modules.

This configuration enables Routing over ATM using LAN Emulation (LANE). LANE can be tunneled across the WAN through the DS-3 link.
