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 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, and a 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.

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.

7. A program for implementing a network management apparatus, wherein said program is read and executed by a computer to implement following means on said computer, namely:
-
a collection means for collecting addresses assigned respectively to network elements belonging to an object network managed from said network elements, an acquisition means for acquiring address definition information that defines logical hierarchical structure of the managed network, a configuration analysis means for classifying the addresses of the network elements collected by said collection means into logical networks in each of the logical layers of the managed networks specified by the address definition information acquired by said acquisition means, and for defining define hierarchical relationships between the logical networks, and a monitoring screen generation means for generating information of a network monitoring screen for each logical network representing a network configuration in a layer unit just under the logical network in question, according to the hierarchical relationships of said logical network defined by said configuration analysis means.

8. A network management method for managing a network configuration, comprising steps of:
-
collecting addresses assigned respectively to network elements belonging to a managed network, from said network elements;
acquiring address definition information defining logical hierarchical structure of the managed network;
classifying the collected addresses of the network elements into logical networks in each of the logical layers of the managed networks specified by said address definition information acquired, and defining hierarchical relationships between the logical networks; and
generating information on 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 above-defined hierarchical relationships of said logical network.
