<p><P>PROBLEM TO BE SOLVED: To avoid re-configuration of divided packet in a relay node and re-dividing processing in a system for converting a destination address to perform multicast in a pseudo way. <P>SOLUTION: A server side gateway 2 uses the destination of an IP header as the address of an apparatus corresponding to transmission source of a multicast packet and an address of a delivery table 8, stores the transmission source of the multicast address and destination in an IP option header, and generates a unicast packet in which the multicast packet is stored after the IP header and the IP option header and transmits the unicast packet. A relay node 3 changes the address of the IP header of the received unicast packet into the address of a device corresponding to the transmission source and address of the IP option header of the unicast packet in the delivery list, and transmits the received unicast packet. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
