ARRANGEMENT IN A ROUTER OF A MOBILE NETWORK FOR OPTIMIZING USE OF MESSAGES CARRYING REVERSE ROUTING HEADERS

摘要

A mobile router is configured for optimized utilization of reverse routing headers, to specify a path between an originating mobile router and a home agent. Reverse routing headers enable each mobile router within the path to the home agent to specify its care of address, enabling the home agent to establish a bidirectional tunnel to the originating mobile router via the corresponding mobile router. The mobile router selectively updates the rever se routing header in a received packet by inserting the source address value of the received packet into the reverse routing header and inserting its corresponding care of address into the specifies reachability of a most rece nt entry in the reverse routing header via the source address value. The mobile router also may request the originating mobile router to increase the revers e header size.
