Abstract

Provided is a policy based management system such that a policy enforced by each router (a managed device) in a network can be optimally adjusted in real time according to a traffic usage. At a managed device 3 in a network NT, there is provided: a policy enforcement means 31 for enforcing policy information distributed from a management device 2, thereby controlling a traffic; a policy evaluation means 32 for evaluating a policy based on policy evaluation information distributed from the management device 2; and a policy adjustment means 33 for dynamically adjusting the policy based on the policy adjustment information distributed from the management device 2 and the evaluation result caused by said evaluation means.

Claims

1. A management device in a policy based management system for managing policy information by means of the management device, and distributing the policy information to the managed device, thereby controlling a traffic, said management device comprising:

a policy information input means for inputting policy information;

a policy evaluation information input means for inputting evaluation information for evaluating an enforcement effect of a policy in the managed device;

a policy adjustment information input means for inputting adjustment information for dynamically adjusting, a policy operated by the managed device; and

a distribution means for distributing the input policy information, policy evaluation information, and policy adjustment information to the managed device.

2. A management device in a policy based management system as claimed in claim 1, wherein said policy evaluation information contains information for judging whether or not a policy assigned to each traffic conforms to the traffic, and said policy adjustment information contains information for ensuring that a policy judged as nonconformance conforms to said traffic.

3. A management device in a policy based management system as claimed in claim 2, wherein said policy evaluation information contains information for judging whether or not a policy under operation is insufficient in resources relevant to an actual traffic, and said policy adjustment information contains information for reducing resource insufficiency of a policy.

4. A management device in a policy based management system as claimed in claim 2, wherein said policy evaluation information contains information for judging whether or not a policy under operation is insufficient in resources relevant to an actual traffic, and said policy adjustment information contains information for reducing resource excess of a policy.

5. A managed device in a policy based management system for managing policy information by means of the management device, and distributing the policy information to the managed device, thereby controlling a traffic, said managed device comprising:

a policy enforcement means for enforcing a policy information distributed from the management device, thereby controlling a traffic;

a policy evaluation means for evaluating a policy under operation based on policy evaluation information distributed from the management device; and

a policy adjustment means for dynamically adjusting a policy under operation based on the policy adjustment information distributed from the management device and the evaluation result obtained by evaluation means.

6. A managed device in a policy based management system as claimed in claim 5, wherein said policy evaluation means evaluates whether or not a policy assigned to each traffic conforms to the traffic, and said policy adjustment means ensures that the policy conforms to the traffic based on said evaluation means.

7. A managed device in a policy based management system as claimed in claim 6, wherein said policy adjustment means reduces network resources assigned by a policy evaluated as a resource excess by said evaluation means.

8. A managed device in a policy based management system as claimed in claim 6, wherein said policy adjustment means improves a quality of a policy evaluated as resource insufficiency by said evaluation means.

9. A managed device in a policy based management system as claimed in claim 5, wherein said policy adjustment means adjusts a policy assigned to each traffic in advance based on the evaluation result obtained by said evaluation means.

10. A managed device in a policy based management system as claimed in claim 5, further comprising a notifying means for notifying the policy information after adjusted to at least one of a management device and another managed device.

11. A managed device in a policy based management system as claimed in claim , where in said policy adjustment means adjusts a policy based on the notification from another managed device.
