LAN emulation network node interface (LNNI)
The LAN EmulationNetwork NodeInterface (LNNI) is a standardized interface between two LAN servers, for example between two LAN Em ulation Servers ( LES-LES) or two Broadcast and Unknown Serv ers ( BUS-BUS), between LAN Emulation Configuration Servers ( LECS-LECS) and between LAN Emulation Configuration Server(LECS) and LAN Emulation Server ( LEC). Since LAN Emulation ( LANE) over large networks requires multiple LAN Emulation Servers (LES), but the LANE 1.0 specification specifies only one LES, the LNNI was specified, which is part of LANE 2.0.
