Patent ID: 8711870

Claim:
A method of handling traffic via a dual homing configuration connecting two communication networks, wherein the dual homing configuration comprises two peers GWs in a first network and at least one network element NE in a second network, the two GWs being connected to one or more common Source nodes, two paths, respectively passing through the two GWs being formed between a specific source node and said at least one NE, and among the two paths, during operation, one path is a currently main path and the remaining path is a currently auxiliary path for a specific traffic service method comprising: transmitting said specific traffic service between the specific common Source node and said at least one NE via the dual homing configuration; redirecting the specific traffic service from one of said paths to another while both of said paths are active; and relearning MAC addresses, due to said redirecting, without executing a MAC addresses flush operation in said specific Source node.
