Abstract:

The policy-based approach has been an important means of managing distributed systems and networks. However, conflicts can cause undesirable system be  haviors. According to the protocol levels on which they are acting, policies are classified into the application level and the network level. Based on t he two-level policy architecture, the origins of policy conflicts are explored, and the algorithms of detecting and resolving the inconsistencies betwee n policies are surveyed. Then the benefits and shortcomings of these methods are investigated. Finally, some of the future research directions and open   problems are discussed.
