Summary: | PROBLEM TO BE SOLVED: To achieve update of a preliminary system integrated network tracking the change of network resource, or the like, while reducing the amount of resources used of a network management device.SOLUTION: In a communication system including a plurality of communication devices connected via a link, and a management device for managing an integrated network constituted of a plurality of paths housing a plurality of services, respectively, via the plurality of communication devices, the management device has an integrated network generation unit for holding the integrated network management information including the cost indicating the usage efficiency of the band of link of a preliminary system integrated network, and generating an active system integrated network and a preliminary system integrated network, and a cost determination unit for determining whether or not it is required to change the configuration of the preliminary system integrated network, based on the cost and a cost threshold, and outputting a regeneration instruction of the preliminary system integrated network to the integrated network generation unit.SELECTED DRAWING: Figure 2
【課題】網管理装置のリソースの使用量等を低減しつつ、網リソースの変化等に追従した予備系統合ネットワークの更新を実現する。【解決手段】リンクを介して接続される複数の通信装置と、複数の通信装置を経由し、複数のサービスの各々を収容する複数のパスから構成される統合ネットワークを管理する管理装置とを備える通信システムであって、管理装置は、予備系統合ネットワークのリンクの帯域の使用効率を表すコストを含む統合ネットワーク管理情報を保持し、現用系統合ネットワーク及び予備系統合ネットワークを生成する統合ネットワーク生成部と、コスト及びコスト閾値に基づいて、予備系統合ネットワークの構成を変更する必要があるか否かを判定し、予備系統合ネットワークの再生成指示を統合ネットワーク生成部に出力するコスト判定部と、を有する。【選択図】図2 |
