METHODS FOR OPTIMIZED TUNNEL HEADERS IN A MOBILE NETWORK

摘要

A sending device replaces (204, 206, 208) an original Internet Protocol (IP) header in a packet with a shim that includes information copied from the IP header, such that the resultant packet being sent from a source device to a destination device has a shim that is smaller in byte size than the header that it replaces. The receiving device copies some different information from the original header into another header. The sending device can further optimize the packet by: eliminating an IP header associated with a security protocol; eliminating a mobility tunnel for a node behind a mobile router (MR); and selective use of a security tunnel for the MR. A receiving device, upon receiving the optimized packet, restores the original IP header using the information in the shim (and other header(s)) and restores any other headers that were removed prior to forwarding the packet toward its intended destination.
