MANAGEMENT METHOD AND MANAGEMENT DEVICE

To provide a management method and a management device, capable of maximizing a path bandwidth while achieving utilization efficiency of resources of the whole system of equal to or higher than a target value.SOLUTION: A service path management device 10 includes: a resource allocation section 13 which calculates a resource utilization efficiency in order of increasing value, in a path bandwidth where a resource amount allocated to a processing function is a maximum value, and which determines, as a path bandwidth set to the processing function, a maximum value in a path bandwidth where the resource utilization efficiency is equal to or higher than a target value and the resource amount is a maximum value; and a path setting section 14 setting the path to each processing function and allocating resources according to a determined path bandwidth.SELECTED DRAWING: Figure 1 【課題】システム全体のリソース使用率を目標値以上にしながら、パス帯域を最大にできる。【解決手段】サービスパス管理装置１０は、処理機能に割当てられたリソース量が極大値となるパス帯域のうち、大きい値から順にリソース使用率を算出し、リソース使用率が目標値以上となる、リソース量が極大値となるパス帯域の最大値を、処理機能に設定するパス帯域として決定するリソース割当部１３と、パスを各処理機能に設定し、決定されたパス帯域に応じたリソースの割り当てを行うパス設定部１４とを有する。【選択図】図１
