<P>PROBLEM TO BE SOLVED: To reduce quantity of identifiers attached to a packet when the packet with the identifiers has failed to be transferred between relay devices. <P>SOLUTION: A relay device 10 has a path information storage unit 102, a key information storage unit 103, a second processing unit 106, an identifier generation unit 109, a transmission unit 112, etc. The path information storage unit 102 stores the final transmission destination address in association with the next transmission destination address. On receiving a packet without identifiers, the identifier generation unit 109 generates an identifier by using a common key extracted from the key information storage unit 103 based on the next transmission address to generate a packet, and the transmission unit 112 transmits the generated packet. <P>COPYRIGHT: (C)2013,JPO&INPIT |
