    • The present invention provides a technique suitable for configuration management of a network for which the number of logical network layers can be set. A network management apparatus 10 receives an address definition information file defining logical hierarchical structure of an IPv6 network 20, from an operator through a definition information reception unit 103. A configuration analysis unit 104 generates management tables defining hierarchical relationships of logical networks, based on the address definition information file and IP addresses collected respectively by an information collection unit 102 from network elements belonging to the IPv6 network 20, and registers the management tables into a management DB unit 101.
    • 本发明提供适用于可以设置逻辑网络层的数量的网络的配置管理的技术。 网络管理装置10通过定义信息接收单元103从操作者接收定义IPv6网络20的逻辑分层结构的地址定义信息文件。 配置分析单元104基于地址定义信息文件和信息收集单元102分别由属于IPv6网络20的网络单元收集的IP地址,生成定义逻辑网络层次关系的管理表,并将管理表注册到 管理DB单元101。
