<p>A route setup server has a storage unit a route designing unit Next hop information indicating candidates of a next hop node for each node is stored in the storage In response to a route setup request specifying a source node and a destination node of flow, the route designing designs a communication route between them. Specifically, the route designing unit has a next hop determination unit that executes "next hop determination it processing" with reference to the next hop information In the next hop determination processing, the next hop determination unit randomly selects one from the candidates of the next hop node regarding a target node and updates the target node to the selected one. The next hop determination unit determines the communication route one-hop by one-hop by initiating the target node to the source node and then repeating the next hop determinai!on processing unfit the target node becomes the destination node,</p> |
