<p><P>PROBLEM TO BE SOLVED: To provide a packet transfer device transferring a packet according to an address including geographic information, without performing functional append or exchange for all of existing routers. <P>SOLUTION: The packet transfer device according to the present invention is a GIP packet transfer device for transferring a packet according to geographic information. The device comprises: a means for saving a routing table of GIP packet transfer; a means for determining whether a received packet is a GIP packet, an encapsulated GIP packet; a means for determining other GIP packet transfer device to which a GIP packet should be transmitted, on the basis of an area specified by the geographic information and the routing table, when the received packet is a GIP packet or an encapsulated GIP packet; and a means for transmitting an encapsulated GIP packet when transmission to the other GIP packet transfer device travels via a packet transfer device which does not recognize geographic information of a destination address of the GIP packet. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
