<p>PURPOSE:To utilize other resource of a network effectively and to improve the service before the restriction is implemented depending on the congestion of a specific node by informing a passing coefficient to each node from a network management center and allowing each node to select an optimum path based on the passing coefficient. CONSTITUTION:A network management center 110 gives a command to a passing coefficient revision means 12 via a traffic control means 11 by a command of the operator. The means 12 informs the passing coefficient to be revised to a passing coefficient storage means 41 of an object exchange node 40. A passing degree calculation means 45 calculates the degree of passing for each relay line based on the operation of an adjacent node from a dialing state operation degree storage means 44 and information from the means 41. A path selection means 46 compares the passing degree of each relay line to select the relay line whose degree of passing is maximum among usable relay lines. Thus, before the restriction is implemented due to the congestion state of a specific node, the other resource of the network is utilized effectively and the service is improved.</p> |
