Abstract:
A LAN Emulation Client (LEC) resiliency method comprising:providing a first and a second Asynchronous Transfer Mode (ATM) interfaces said first and second ATM interfaces being operable for use by a single LEC for controlling data communication; establishing an ATM network connection and using said first ATM interface for data communication over said ATM network connection; associating said single LEC with said second ATM interface if said first ATM interface fails using a first resiliency configuration parameter (RCP), said first RCP operable to specify said first or said second ATM interface as an active LEC interface to said ATM network; and invoking, by said LEC, a join procedure, said join procedure operable to join said LEC to an Emulated Local Area Network (ELAN) coupled to said ATM network using said second ATM interface in response to a failure of said first ATM interface.
