Internet端到端性能监测与分析系统的关键技术研究

Crucial Technology Study of Internet End-to-End Performance Monitoring and Analysis

摘要: 随着网络的不断发展,Internet的正常运行变得越来越重要.基于端到端行为测量特点和主动测量方法,开发了一个分布式大型网络性能监测和在线分析系统——NIPMAS,该系统实现了对大型网络的性能管理和初步的故障管理.主要介绍NIPMAS采用的关键技术:(1)主动测量应用到网络性能监测系统的方法;(2)提出网络监测模型LNM和层次化网络概念,将GIS有效地应用到了NIPMAS中;(3)提出一种大型网络的故障定位方法.

Abstract: A distributed network performance monitoring and on-line analysis system——NIPMAS was developed to realize performance management and rudimentary trouble shooting of large-scale network.It is based on end-to-end paths measurement and active measurement.Three critical techniques used in NIPMAS are illustrated,namely：（1） How to apply active measurement to network performance monitoring and on-line analysis；（2） How to realize the concepts of level network monitoring model LNM for hierarchical network and introducing GIS into NIPMAS；（3） How to locate fault and confine it within a network segment.
