More Information
Summary:A path table, a topology table and a level-of-service agreement table are stored in a storage device of a monitoring control apparatus. A path in which a communication fault occurs is determined based on the path table. The service levels small in terms of an upper limit value of a service cutoff time in emergency are sequentially extracted from the level-of-service agreement table. A path route calculation process is performed on at least one path coincident with the extracted service level, based on the path table. A path route optimization process is performed on at least one path route subjected to the route calculation. An execution result of the path route optimization process is registered in a path calculation result table.
