Abstract

A network management device for managing a plurality of network elements has a network element management data acquisition unit for acquiring, in stages, various management data possessed by the network elements when a session with a network element is resumed and when the network management device itself is started up, a rule management table for storing a dependence relationship between an operation and management data necessary to execute the operation, a feasible operation decision processing unit which, when an operation has been specified, refers to the dependence relationship to determine whether management data necessary to execute the operation has been acquired. If the necessary management data has been acquired, a network management execution unit executes network management conforming to the operation.

Dependent claims

A network management device for managing a plurality of network elements interconnected by a communication network, wherein the network management device is connected to each of the network elements via a management network and comprises:

network element management data acquisition means for acquiring, in stages, various management data possessed by the network elements when a session with a network element is resumed and when the network management device itself is started up;
operation dependence rule storage means for storing a dependence relationship between an operation relating to network management and management data necessary to execute network management that conforms to said operation;
means for referring to the dependence relationship, when an operation has been specified, for determining whether management data necessary to execute the network management that conforms to the operation has been acquired;
and
means for executing the network management that conforms to said operation in a case where the necessary data has been acquired;
whereby an operation for which management data necessary for executing the network management has been acquired is made utilizable before all of the management data concerning each of the network elements is acquired by the network element management data acquisition means.

3 more elements

network element management data acquisition means for acquiring management data possessed by the network elements;
storage means for storing the management data acquired by said network element management data acquisition means;
and
network management execution means for executing processing, which conforms to an operation relating to network management, using the management data that has been acquired, and outputting results of this processing;
said network element management data acquisition means having traffic data acquisition means;
said traffic data acquisition means acquiring traffic data over a prescribed period of time for each management category of each managed object, and storing the traffic data acquired in said storage means in the form of a three-dimensional matrix structure in which managed object, management category and period of time serve as variables.
