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.
