Communication route optimization controller and communication route optimization method

摘要

When the two end nodes that are away from home [PROBLEMS] itself performs data communication, to optimize the route for the data communication. In the header of the packet to be sent correspondent node subordinate to the MR141 against (LFN151), [MEANS FOR SOLVING PROBLEMS] communication node (initiator node 174) adds a destination predefined options, including the home address of its own. When you tunnel to MR this packet, HA121 of the MR, is inserted into the tunnel packet header by copying the destination options given. When transferring the packet to the communication node under, if the check destination option given to whether it is inserted into the tunnel packet header, destination options given are inserted into the packet, MR is the predetermined to start the route optimization process between the (home address included in the destination option specified) the sender of the packet containing the destination options.
