ABSTRACT:
A method for allocating a geographical identifier is executed in a network for supporting a plurality of movable hosts being moved among a plurality of sub networks as keeping communications therebetween. When movable hosts 100, 101 moves to a sub network 110, an agent 120 of the sub network 110 allocates the same geographical identifier depending on the sub network 110 to the movable hosts 100 and 101 and stores logical identifiers and link layer addresses of the movable hosts 100 and 101. The packets destined for the movable hosts 100 and 101 are sent to the agent 120. The agent gets to know the link layer address corresponding to the logical identifier of a destination movable host described in a network layer header of the received packet from the registration table, generates the link layer header of the destination movable host, and add the link layer header to the received packet before transferring the received packet.
