Abstract: In an MB management system, a user who wishes to use a network service sends MB requirements from a user terminal to a network management apparatus, which is managed by a provider who provides a network service. The network management apparatus returns to the user terminal abstract models as a guide for the performance and the like of MBs that are available in the network service and that meet the MB requirements. The user operates the user terminal to select an MB that the user is to use from among the provided abstract models. The user also receives via the user terminal from the network management apparatus the operational status of an instance of the MB selected from among the abstract models. This allows the user to compare the MB requirements presented by the user and the actual operational status of the MB instance.
