ABSTRACT:
A method and apparatus for tunnel packet optimization is provided. A method for communications node operation where the communications node is at a beginning of a tunnel includes receiving a message from a communications device at an end of the tunnel, processing a packet having a first source address and a first destination address, and encapsulating the packet with an outer header having a second source address and a second destination address, thereby producing a tunnel packet. The message includes a flow label related to the first source address and the first destination address. The method also includes compacting the tunnel packet based on a tunnel optimization (TO) state, and transmitting the tunnel packet towards the second destination address. The second destination address includes an address of the communications device at the end of the tunnel.
