Summary:PROBLEM TO BE SOLVED: To reduce the maintenance cost of a network, and also to quickly and efficiently provide a user with a network service.SOLUTION: A network management device M comprises: an infrastructure manager unit 2 which manages an IA server, a VM (virtual server), and a core NW-side device (core router and the like) arranged on a core NW, and an access NW-side device (L2SW and the like) arranged on an access NW; and an orchestrator unit 1 which acquires an NS (Network Service) generation request from a host device U. The orchestrator unit generates a VM on which an NW function (APL) operates on the basis of an NS generation request, sets connection points in the NW function, the IA server on which the generated VM operates, the core NW-side device, and the access NW-side device, and generates an NS slice over the core NW and the access NW by connecting the connection points by a link.SELECTED DRAWING: Figure 1 【課題】ネットワークの保守コストを削減するとともに、ユーザへのネットワークサービスの提供を迅速化、効率化させる。【解決手段】ネットワーク管理装置Mは、コアNWに配置されているIAサーバ、VM(仮想サーバ)、コアNW側装置(コアルータなど)、および、アクセスNWに配置されているアクセスNW側装置(L2SWなど)を管理するインフラマネージャ部2と、NS(Network Service)生成要求を上位装置Uから取得するオーケストレータ部1と、を備え、NS生成要求に基づいて、NW機能(APL)が動作するVMを生成し、NW機能、当該生成されたVMが動作するIAサーバ、コアNW側装置、および、アクセスNW側装置に接続点を設定し、当該接続点をリンクで接続することで、コアNWおよびアクセスNWに亘るNSスライスを生成する。【選択図】図1
