<p>A secondary edge node is coupled between the packet network and a non-packet network and is adapted to function as follows when a failure associated with the primary edge node or circuitry coupled thereto occurs. First, the secondary edge node may detect a failure associated with the primary edge node, which is associated with a primary media access control (MAC) address that is used to direct the packet traffic from the first edge node to the primary edge node. Upon detecting the failure, the secondary edge node may send a switch request message including a secondary media access control address that is associated with the secondary edge node to the first edge node. Sending the switch request message indicates that the first edge node should start sending traffic for the first session to the secondary edge node using the secondary media access control address.</p> |
