摘　　要：分布式网络性能监测的关键问题是如何在管理域中的适当位置放置适当数目的代理,才能达到提高监测效率,减小额外监测流量和响应时间的目的。本文提出的算法是在管理员改变网络拓扑结构或者网络节点或链路失效时被启动,能够针对网络的变化自动地进行局部监测代理分布的调整,使监测系统恢复到近似最优状态。该算法使本监测系统具有良好的可扩展性和适应能力,仿真实验证明了算法的可行性。One of the critical problems in distributed network performance monitoring is that how to place proper number of monitoring agents in proper locations in a managed network can improve monitoring efficiency, that is, decrease monitoring traffic and response time. Our algorithm was triggered when network topology changed, or nodes and links failures occurred. By adjusting some agents＇ deployment, it could draw the whole monitoring system back to proximate optimization state. Simulation shows that this algorithm can add flexibility and scalability to the proposed monitoring system.
