基于流量工程的网络性能监测和控制系统

网络性能的监测和控制是网络得以正常运行的重要环节。网络流量工程提出了网络性能评价的原理、体系和方法。文章对CERNET（中国教育与研究计算机网）主干网、CERNET到国际互联节点、CERNET到国内八大网络节点，提出基于网络流量工程的性能监测和控制的实现方案，并实现了端到端网络性能的测量和分析，为基于MPLS的网络性能优化和控制提供了有利的依据。通过该系统的实施，可以在CERNET主干网上建立Q－Bone，为高速网络应用提供服务质量的保证。

Measurement and Control System of Internet Dynamics Based on Traffic Engineering

： Internet traffic engineering is defined as that aspect of Internet network engineering dealing with the issue of performance evaluation and performance optimization of operational IP networks．Traffic Engineering encompasses the application of technology and scientific principles to the measurement，characterization，modeling，and control of Internet traffic．With the internationalization and advancement of CERNET＇s operation and management，it＇s necessary to create the measurement and control system in the backbone of CERNET．The system includes three parts：the measurement of end－to－end network traffic，the analysis of the raw data and control based on MPLS．As a result of the application of the solution，we will be able to create Q－Bone in CERNET to provide guaranteed traffic service in high speed．
