Abstract:
A method to provide enhanced peer redundancy to an Asynchronous Transfer Mode (ATM) emulated local area network (ELAN) wherein the ELAN is served by a primary LAN emulation server (LES), a broadcast and unknown server (BUS) and a LAN emulation configuration server (LECS), the method comprising the steps of:coupling a peer LES/BUS to the ELAN; establishing an enhanced peer redundancy virtual channel connection (VCC) between the primary LES/BUS and the peer LES/BUS; transmitting a plurality of status messages between the primary LES/BUS and the peer LES/BUS; comparing a first number of LAN emulation clients (LECs) joined with the primary LES/BUS and a second number of LECs joined with the peer LES/BUS; and providing ELAN services to all of the LECs in the ELAN by the LES/BUS having a greater number of joined LECs.
