ACCESS ROUTER FOR GUARANTEEING MOBILITY OF MOBILE NODE AND METHOD FOR GUARANTEEING MOBILITY OF MOBILE NODE IN THE MOBILE NODE

摘要

A method for guaranteeing the portability of a mobile node and an access routing device for providing data transmission path are provided to perform any-cast routing by setting a static IP of the mobile node to the access router. An address acquiring unit(110) acquires internet protocol address information of the mobile node from the mobile node. An address setting unit(120) sets up the obtained internet protocol address information as the anycast internet protocol address. A routing information transmitting unit(130) produces the routing information about the set up anycast internet protocol address. The generated routing information is delivered to the other router. A packet transmitting unit(150) has the anycast internet protocol address as the destination location and the packet transmitted through the anycast routing.
