Communication network managing system, element and network managers therefor, and computer-readable recording medium in which communication network managing program is recorded

Abstract

In a communication network managing system, at a network manager, a management section manages QoS (Quality of Service) capability management information from element managers, a request reception section receives a request for a target QoS capability, and a section and notification section selects a candidate subnetwork such as to satisfy the target QoS capability for which the request has been received by the request reception section, and notifies the corresponding element managers of information about the selection. At the individual element manager, based on the selection information from the selection and notification section of the network manager, a control section controls the corresponding subnetwork.
