Abstract
In a high-speed routing control system, plural path candidates each leading to a destination node are selected on the basis of physical connection information of links connecting respective nodes in a path candidate selection unit 11, and a path candidate containing no congestion-occurring link is specified as the optimum path from the plural path candidates selected by the path candidate selection unit 11 in an optimizing unit 12. Accordingly, even when the destination node is nearer to the self node, the optimum path selection can be performed, and a switching operation to a bypass path can be performed at high speed. In addition, the traffic amount based on topology information can be suppressed, and the large-scaling of the network can be supported.
