An Automatic Policy Refinement Mechanism for Policy-Driven Grid Service Systems

摘要

Currently, the management of grid services is becoming increasingly complex. To resolve this complexity problem, autonomic computing and policy-based multi-agent technology have been proposed as promising methods. However, there are many challenges to be resolved. Among them, policy refinement is a great problem that hampers the development of policy-based system. To cope with this issue, this paper presents a policy refinement mechanism based on recipes. Recipes define possible refinement alternatives for each abstract policy. And the policy refinement engine automatically refines the policies by choosing the refinement branch in terms of the conditions of each branch.
