1. A computer network management system comprising:
- a communication network having a policy-based manager means distributed across said network,the distributed policy-based manager comprising a plurality of distributed management agents arranged in a hierarchy and being associated with sub-networks of said network, each of said agents includes means to register local network components with itself, to identify and store one or more roles associated with the component and to obtain policies relevant to the stored roles of the registered components,wherein each of the policies are locally stored and specify a subject role identifying the components in the system which are expected to respond to a policy and an action element specifying an action to be carried out.

Abstract
A computer network is managed by policies. This allows selections to be made from a range of control options and optionally to be based on locally available system information. Policy-based management is distributed across the system and is handled locally by management agents allowing control of a sub-network. As a result of a distributed policy-based management system is provided which allows additional flexibility of control.
