策略检查与冲突避免方法研究

Research on the Method of Policy Inspection and Conflict Avoidance

策略检查与冲突避免是基于策略的网络管理框架中的一个重要研究内容,为了维护系统处于良好的运行状态,必须具有能够确保策略合法性、有效性和一致性的检查机制。提出基于多维空间的全局冲突检测方法,对策略的有效性进行判定;对策略进行必要的验证以免策略存在语法或语义上的冲突。研究有效的策略冲突消解方法,实现基于有向无环图的策略冲突避免算法。

Policy inspection and conflict avoidance is an important research in PBNM （Policy Based Netwoek Management）. This paper proposes a global conflict avoidance method with the knowledge of multi-dimensional space. In this method, the availability of the policy is firstly inspected, and then the policy is validated to keep away from the syntax errors and solve the semantic conflicts. This paper also researches on all kinds of conflict avoidance methods, and proposes an algorithm based on the directed acyclic graph at last.
