Abstract: Provided is a management system arranged to manage a plurality of network elements in a network. The management system specifies, when the management system receives an alarm event, a logical path corresponding to the received alarm event based on the logical path specifying information included in the received alarm event. The management system refers to the logical path management information and specifies an alarm spread logical path of the specified logical path. The management system correlate the received alarm event and the specified logical path, correlate the received alarm event and the specified alarm spread logical path, and register the correlations with the alarm spread logical path information.

Abstract: 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.
