Policy-based Approach to Detect and Resolve Policy Conflict for Static and Dynamic Architecture

Current research efforts are being directed to commit with the long-term view of self-management properties for wireless telecommunications. One of the key approaches that have been recognized as an enabler of such a view is policy-based management. Policy-based management has been mostly acknowledged as a methodology that provides flexibility, scalability, adaptability and support to automatically assign network resources, control Quality of Service and security, by considering administratively specified rules. The hype of policy-based management was to commit with these features in run-time as a result of changeable network conditions resulting from the interactions of users, applications and existing resources. To detect and resolve potential static and dynamic conflicts between the rules and configurations from different administrative domains, a policy-based manager coordination PobMC framework which is based on EventCondition-Action (ECA) is proposed in this paper. The framework is responsible of potential conflicts between applications included in the system. Furthermore, the paper provides a guideline to avoid policy conflicts between different domains configurations, and resolve the conflicts during runtime. PobMC depends on, static and dynamic analysis to reduce potential conflicts. The paper briefly outlines some of the most prominent research issues that have been discussed for large-scale adoption of policy-based systems. Then we present a description of the conflict detection and resolution algorithms that achieves the automated enforcement of obligations for resource-handling based on management policies.
