NETWORK MANAGEMENT SERVER AND RECOVERY METHOD

摘要

A network management server stores, in terms of a transmission path within the network, each occurrence pattern of a failure occurrence area in which a failure has occurred in a communication apparatus through which the transmission path passes. Information for identifying a recovery plane serving as a set of recovery paths corresponding to each occurrence pattern and information for identifying the communication apparatus through which each of the recovery paths passes is also stored. When a failure occurs in any one of the plurality of areas, whether or not the failure corresponds to any one of the failure occurrence patterns, the information for identifying the recovery plane corresponding to the identified failure occurrence patterns is acquired; and the communication apparatus through which each of the recovery paths included in the recovery plane passes is notified of the information for identifying the recovery plane acquired.

主权项

1. A network management server to be coupled to communication apparatus within respective areas of an area group forming a network, the network management server comprising:
a processor for executing a program; a memory for storing the program to be executed by the processor; an interface for controlling communications to/from each of the communication apparatus; and a storage for storing data, wherein: the storage stores, in terms of a transmission path within the network, for each occurrence pattern of a failure occurrence area in which a failure has occurred in the communication apparatus among a plurality of areas through which the transmission path passes: information for identifying a recovery plane serving as a set of recovery paths corresponding to the each occurrence pattern; and information for identifying the communication apparatus through which each of the recovery paths passes, in association with each other; the communication apparatus each store recovery information comprising:
information for identifying the recovery plane serving as the set of recovery paths passing through an own apparatus; andinformation for designating coupling counterparts to which the own apparatus is to be coupled in each of the recovery paths passing through the own apparatus; and the network management server executes:
an identification procedure of identifying, when a failure occurs in any one of the plurality of areas, whether or not the failure corresponds to any one of failure occurrence patterns;an acquisition procedure of acquiring the information for identifying the recovery plane corresponding to the one of failure occurrence patterns identified in the identification procedure from the storage; anda notification procedure of notifying the communication apparatus through which each of the recovery paths included in the recovery plane passes of the information for identifying the recovery plane acquired in the acquisition procedure.
