Abstract
To insure connection resiliency two LECs are defined in normal practice in which a lengthy and extensive recovery procedure is enforced in case of an ATM interface failure. In the present invention only one LEC is configured. This LEC is configured to be If the active ATM interface fails, the bridge is not notified of the failure as would normally happen. The LEC associates itself with the alternate ATM and rejoins the ELAN via the alternate ATM interface. The ELAN Join Procedure is one of the LAN Emulation protocols. After the ELAN has rejoined, the LEC automatically re-establishes the previously existing Data Direct VCCs (bi-directional point to point LAN Emulation connection established from one LEC to another) using its LE_ARP (LAN Emulation Address Resolution Protocol) cache entries.
