策略冲突的检测和解决方法研究

Detecting and Resolving Policy Conflicts

基于策略的方法在分布式系统和网络管理领域已得到广泛实施。策略中的冲突会导致不一致的系统行为根据策略所作用的协议层次,将策略分为应用级和网络级两类。本文深入研究了每一类策略的冲突现象,并综述了冲突的检测和解决方法,对其优缺点加以分析;最后给出了未来的研究方向。

The policy-based approach has been an important means of managing distributed systems and networks. However, conflicts can cause undesirable system behaviors. According to the protocol levels on which they are acting, policies are classified into the application level and the network level. Based on the two-level policy architecture, the origins of policy conflicts are explored, and the algorithms of detecting and resolving the inconsistencies between 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.
