First Claim
Patent Images
1. A computer network management system comprising a distributed policy-based manager which comprises, for each of a plurality of sub-networks of said computer network management system, an associated management agent, each sub-network including a store arranged to store policy-conflict resolution policies for one or more components in said sub-network, wherein each said sub-network management agent incorporates:
- (i) a sub-network policy receiver configured to receive policies from a policy store external to said associated management agent;
(ii) a policy-conflict resolution mechanism arranged in operation to resolve at run time conflicts between different policies received by said sub-network policy receiver taking said stored policy-conflict resolution policies into account.

Abstract
A computer network includes a plurality of components governed by policies from a policy manager. Where conflicts arise between policies, a conflict management policy is inherent in the system and is implemented to detect and resolve such conflicts.

6. A method of distributed policy management in a computer network which includes a plurality of sub-networks, said method comprising:
-
(i) configuring a plurality of interconnected components to have behavior determined by a plurality of policies; (ii) associating a sub-network management agent with each said sub-network; (iii) storing in each sub-network, policy-conflict resolution policies for one or more components in said sub-network; (iv) operating each associated sub-network management agent to; (a) receive policies from a policy store external to said associated management agent; and (b) determine at run time if, in respect of any given triggering event, a possible conflict may arise in respect of one or more of said received policies activated by said triggering event and, if so, passing each respective activated policy as an argument to a policy-conflict resolution process operating, as part of each sub-network management agent, in accordance with said stored policy-conflict management policies. - View Dependent Claims (7, 8, 9)

10. A computer-readable computer program storage medium containing a program or a suite of programs comprising processor implementable instructions for causing a computer processor to carry out a method comprising:
-
(i) configuring a plurality of interconnected components to have behavior determined by a plurality of policies; (ii) associating a sub-network management agent with each said sub-network; (iii) storing in each sub-network, policy-conflict resolution policies for one or more components in said sub-network; (iv) operating each associated sub-network of said management agent to; (a) receive policies from a policy store external to said associated management agent; and (b) determine at run time if, in respect of any given triggering event, a possible conflict may arise in respect of one or more of said received policies activated by said triggering event and, if so, passing each respective activated policy as an argument to a policy-conflict resolution process operating, as part of each sub-network management agent, in accordance with said stored policy-conflict management policies.
