摘要： A network management system includes a plurality of server units. A first management server included in a first server unit transmits a disconnection setting request for disconnecting an abnormal flow to each of a communication node connected to a self-region covered by the first management server, and one or more second server units covering one or more primary adjacent regions adjacent to the self-region. Disconnection setting is executed in response to the disconnection setting request. Each of a plurality of regions includes two or more areas each of which is covered by corresponding one of two or more base stations connected to an identical communication node.

摘要： A communication system is capable of re-examining an allocated communication path and a reserved communication path and implementing a rapid service provision in which a resource utilization efficiency is high without an interruption of service or an abrupt deterioration of quality when a reserved communication path is created in advance, and a reserved communication path is allocated according to an allocation request of a user. A communication path with quality assurance of data communication is implemented in a communication network with a communication path calculation device having a communication path managing unit and communication path calculating unit. The communication path managing unit manages reserved communication paths with quality assurance constructed based on a quality assurance communication path construction request of a communication system administrator and a use communication path allocated from among the reserved communication paths according to the quality assurance communication path allocation request of the communication network user.

摘要： A transfer apparatus is configured to: calculate a total cost of a first route in a first network that starts from a source transfer apparatus and ends at a destination transfer apparatus; obtain a particular cost being a cost between the source transfer apparatus and a first line, which couples the source transfer apparatus and its own transfer apparatus, in a second route, which starts from the source transfer apparatus and reaches the destination transfer apparatus via its own transfer apparatus; calculate a differential between the total cost and the particular cost; set, based on the differential, a cost between its own transfer apparatus and a second line, which couples its own transfer apparatus and the destination transfer apparatus, to a value that causes the source transfer apparatus to select the second route rather than the first route; and notify the cost value to the source transfer apparatus.

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.
