Abstract

A policy rule scenario control apparatus comprises a scenario data storing unit storing one or more scenario data produced by combinations of a plurality of types of policy rules and applying conditions of these policy rules, a monitoring unit monitoring an operating state of a network device, a scenario selecting unit selecting the scenario data having the applying condition suitable to the monitor result, and a scenario implementing unit implementing policy control on the network device on the basis of, in the selected scenario data, the policy rule having the applying condition suitable to the monitor result, and implementing the policy control on the network device on the basis of a result of the implementation and another policy rule having the applying condition suitable to a subsequent monitor result. This enables automatically applying the policy rule validly according to the network state varying at all times.

Claims

1. A policy rule scenario control apparatus comprising:

scenario data storing means storing one or more scenario data produced by combining a plurality of types of policy rules for policy control on a network device and applying conditions of said policy rules;

monitoring means monitoring an operating state of said network device;

scenario selecting means selecting, from said scenario data storing means, said scenario data having the applying condition suitable to a monitor result in said monitoring means; and

scenario implementing means implementing said policy control with respect to said network device on the basis of, in said scenario data selected by said scenario selecting means, said policy rule having the applying condition suitable to said monitor result, and implementing said policy control with respect to said network device on the basis of a result of the implementation and a different policy rule having the applying condition suitable to a subsequent monitor result in said monitoring means.

2. A policy rule scenario control apparatus comprising:

policy data storing means storing, as policy data, a plurality of types of policy rules for policy control on a network device;

scenario data storing means storing one or more scenario data produced by combining said plurality of types of policy rules and applying conditions of said policy rules;

scenario inputting means receiving an input of the applying conditions of the policy data and combining the plurality of types of policy data in said policy data storing means and the applying conditions to produce said scenario data and register said scenario data in said scenario data storing means;

monitoring means monitoring an operating state of said network device;

scenario selecting means selecting, from said scenario data storing means, the scenario data having the applying condition corresponding to a monitor result in said monitoring means; and

scenario implementing means implementing said policy control with respect to said network device on the basis of, in said scenario data selected by said scenario selecting means, the policy rule having the applying condition suitable to said monitor result, and implementing said policy control with respect to said network device on the basis of a result of the implementation and a different policy rule having the applying condition suitable to a subsequent monitor result in said monitoring means.

3. A policy rule scenario control method comprising the steps of:

storing, in scenario data storing means, one or more scenario data produced by combining a plurality of types of policy rules for policy control on a network device and applying conditions of said policy rules;

monitoring an operating state of said network device;

selecting, from said scenario data storing means, the scenario data having the applying condition corresponding to a result of the monitoring;

implementing said policy control with respect to said network device on the basis of, in the selected scenario data, the policy rule having the applying condition suitable to said monitoring result; and

implementing said policy control with respect to said network device on the basis of a result of the implementation and a different policy rule having the applying condition suitable to a subsequent monitoring result.

4. A policy rule scenario control method comprising the steps of:

storing, in policy data storing means, a plurality of types of policy rules as policy data for policy control on a network device, and storing, in scenario data storing means, a plurality of scenario data produced by combining said plurality of types of policy rules and applying conditions of said policy rules;

upon receipt of an input of the applying conditions of said policy data, combining said plurality of types of policy data in said policy data storing means and said applying conditions to produce said scenario data and register said scenario data in said scenario data storing means;

monitoring an operating state of said network device;

selecting, from said scenario data storing means, the scenario data having the applying condition corresponding to a result of the monitoring;

implementing said policy control with respect to said network device on the basis of, in the selected scenario data, the policy rule having the applying condition suitable to the monitoring result; and

implementing said policy control with respect to said network device on the basis of the implementation result and a different policy rule having the applying condition suitable to a subsequent monitoring result.
