PROBLEM TO BE SOLVED: To transmit a packet to a communication destination if a temporary communication failure occurs.SOLUTION: A node 100 transmits the packet to the communication destination according to a routing table. A node 100 determines whether or not communication through a communication route, preset in the routing table, is disabled. When the communication through the preset communication route is disabled, the node 100 refers to a link table, to change over to communication with the communication destination, using a communication route in which relaying nodes 100 is larger in number as compared to the nodes in the communication route in which the communication is disabled.SELECTED DRAWING: Figure 1 |
