Estimating the term…
In a state I, a link layer of a mobile host is connected to an access router and a default router is set to the access router such that data packets (P1) and (P2) reach the access router and are routed to a correspondent host. In states II and III, data packets (P3) to (P8) are not transmitted but are buffered. When the mobile host switches the default router from the access router to an access router upon reception of a router advertisement from the access router, processing moves to a state IV and the buffered data packets (P3) to (P8) are transmitted. Since the link layer of the mobile host is connected to the access router and the default router is set to the access router, the data packets (P3) to (P8) reach the access router and are routed to the correspondent host.
A mobile node for transmitting a packet, comprising means for buffering the packet during a hand-off period and transmitting the buffered packet when the hand-off is complete,
A mobile communication system comprising a mobile node for transmitting a packet and a plurality of access routers for providing said mobile node with an link,
A communication control program which, in order to transmit a packet, causes a computer to function as means for buffering the packet during a hand-off period and transmitting the buffered packet when the hand-off is complete,
