<p>PURPOSE: To make possible intermittent usage even when transfer to a specified transfer destination candidate address is disabled by preparing the routing table corresponding to the number of transfer destination candidate address allowing the second transfer destination candidate to be hopped. CONSTITUTION: A discrimination part 52 compares the presence/absence of first transfer destination candidate addresses as one part of the transfer destination candidate addresses, the number of packets for RIP to be hopped and the number of parts corresponding to a table to be hopped. Then, a first candidate comparing means 521 selects the first transfer destination candidate addresses and its number to be hopped. Besides, the presence/absence of second transfer destination addresses as the other part of transfer destination candidate addresses, the number of packets for RIP to be hopped and the number of parts corresponding to the table to be hopped are compared. Then, a second candidate comparing means 522 selects the second transfer destination candidate addresses and its number to be hopped. Corresponding to these results, a routing table 100 is generated and according to a control part 53, a transmission part 54 performs packet transmission through a transmitting means 542 while referring to the contents in the table 100.</p> |
