MOBILITY CONTROL SYSTEM, MOBILE NODE USED IN THE SYSTEM, MOBILITY CONTROL METHOD, MOBILITY CONTROL PROGRAM, AND MOBILITY CONTROL NODE

摘要

When a mobile node MN moves from an access router AR3 to another access router AR4, it sends a multi-binding on request to a mobility agent MA1 and then moves (1 &cir& ). Receiving the multi-binding on request, the mobility agent MA1 voluntarily configures prospective CoA's (probable CoA's). The probable CoA's are added as forwarding addresses while an M bit is set on in an register of the mobile node MN on a binding cache (2 &cir& ). When the mobility agent MA1 receives a capsuled packet addressed to the mobile node MN thereafter, it tunnel-forwards the packet to CoA3, probable CoA2, and probable CoA4 according to the binding cache (3 &cir& ).
