在介绍策略、域和策略目标等基本概念的基础上,提出了一个通用性的策略部署模型,该模型采用基于域的分层结构,把策略存储在离策略目标最近的域中,并以递增式算法进行收敛变化。模型独立于具体的策略底层实现机制,并可在混合策略环境中使用,具有良好的多适性。Policy based management is an effective approach to manage distributed system and large scale system. With the basic concepts of policy, domain and policy target introduced, a general policy deployment model is purposed which based on domain layer architecture. It assumes that policies are stored in the most close domain to target, and the whole system changes according to the increment arithmetic. The general model is independent of the underlying concrete policy enforcement mechanisms and can be employed in mixed policy environments.
