Network management apparatus and network management method
First Claim
1. A network management apparatus for managing a network configuration, comprising:
- a collection means for collecting addresses assigned respectively to network elements belonging to a managed network, from said network elements,an acquisition means for acquiring address definition information that defines a logical hierarchical structure of the managed network,a configuration analysis means for classifying the address of the network elements collected by said collection means into logical networks in each of logical layers of the managed network specified by the address definition information acquired by said acquisition means, and for defining hierarchical relationships between the logical networks, anda monitoring screen generation means for generating information of a network monitoring screen for each logical network representing a network configuration in a layer just under the logical network in question, according to the hierarchical relationships of said logical network defined by said configuration analysis means,wherein;
said collection means collects element information including an address, connection relationships and element type of the network element in question, from each network element belonging to the managed network,said configuration analysis means defines relay nodes included in each logical network classified by said address definition information according to the element information collected by said collection means from each network element, and defines connection relationships between said relay nodes, andsaid monitoring screen generation means generates information of a network monitoring screen for each logical network by using symbols representing logical networks, referred to as lower-side logical networks, included in the logical network in question and belonging to a layer just under the logical network in question, symbols representing relay nodes included in the logical network in question, and symbols representing connections between the lower-side logical networks and the relay nodes, in order to display said network monitoring screen that represents the network configuration.

Abstract
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.
