Abstract
One embodiment of the present invention provides a system for facilitating session migration. During operation, the system receives a communication packet from a client destined to a remote server. The system determines whether the communication packet belongs to a pre-existing communication session, and whether session state information associated with the session is available locally. In response to the communication packet belonging to a pre-existing communication session and the session state information being unavailable locally, the system constructs an interest requesting the session state information, disseminates the interest over a network, and receives the session state information.
