IP Over ATM and LANE Creating an Emulated LAN
Figure 2-3 LNNI Redundant LECSs on same network
LANE Load Sharing
Running multiple LECSs, alleviates the bottleneck of a single LECS supporting all clients on all ELANs. Under LNNI,
a client requesting a call setup is serviced by the LECS, LES and BUS on the switch that it’s directly connected to,
leaving other SmartSwitch ATM switches free to service the call setups from their directly attached clients (see
Figure 2-4).
