ROUTING OPTIMIZATION METHOD IN THE SAME NESTED NEMO

摘要

A method for optimizing communication path overlapped equal MNs(Mobile Networks) is provided to enable each UE(User Equipment) to communicate each other in fast and efficient ways through mobile path optimization of packets, when the UEs existing within intra-NEMO(Network Mobility) networks communicate together. MRs(Mobile Routers)(21-24) of intra-NEMO networks(11,12) mutually deliver path optimization messages(101-103) including network prefixes of self internal interfaces. All of the MRs(21-24) generate/update forwarding tables(201-203) based on the messages(101-103). When one of the MRs(21-24) forwards packets delivered to the one of the MRs(21-24), the one of the MRs(21-24) compares entries of the tables(201-203) with destination IP(Internet Protocol) addresses of the packets, and forwards the packets to the corresponding interfaces according to information on the tables(201-203).
