基于Policy的网络管理模型的研究与实现

基于policy的网络管理支持管理系统动态扩充，得到越来越多的研究与应用，首先给出了基于policy的网络管理模型，然后定义policy服务器的体系结构和支持协同的基于policy的网络管理框架，管理框架支持管理人员对任务进行分解，用ploicy描述子任务，然后将ploicy分发到policy服务器，由policy服务器解释执行，多个域的ploicy服务器之间可以发送和接收消息以协调地运行，完成全局的管理任务，管理人员可以动态地对ploicy进行修改以适应系统的变化。

RESEARCH AND IMPLEMENTATION OF A POLICY-BASED NETWORK MANAGEMENT MODEL

Policy based network management enables management system to be extended dynamically. It is gaining more and more research and application. A policy based network management model is first, presented and then a policy server's architecture and policy based network management framework supporting cooperation are defined. The management framework supports administrator to decompose task into several subtasks and use policies to describe these subtasks, and then delegate these policies to policy servers to interpret and execute them. Policy servers in different domains can transfer messages between each other to cooperatively work in order to accomplish global management task. Administrator can modify these policies dynamically according to requirements of network's growth.
