<p>PURPOSE:To enable communication to be continued by transmitting a relay loop detecting packet, judging the generation of a relay loop by the return of the packet, and informing a detour to another relay route to each node by transmitting a relay loop information packet. CONSTITUTION:A certain relay node transmits the relay loop detecting packet 2 at the time of generating the excess of the number of times of relay or a residence time. When the realy loop is detected by the return of the packet after the circulation of the relay loop, the relay loop information packet 3 is transmitted to all the nodes (A-F) of the relay loop, and transmission to the relay route which becomes the relay loop is prohibited at each node. In such a way, since a following packet detours the relay loop and performs the transmission to another relay route, the communication can be continued.</p> |
