ABSTRACT:
The system includes a mobile node (101) communicating with a correspondent node (102), a home agent node (131) managing the mobile node (101), a proxy node (121) being located closer to the mobile node (101) than the home agent node (131) and relaying the packets from the mobile node (101) to the home agent node (131), and a routing manager (141) managing a route of the packets. The proxy node (121) detects a trigger of a packet route optimization and notifies the routing manager (141). The proxy node (121) establishes the optimized routing path according to a command received from the routing manager (141) and routes the packets through the established routing path using a secure method.
