网络测量及其关键技术

讨论网络流量测量的常用方法和常用测量指标以及网络流量测量中的关键技术。介绍了时延测量、“噪声”分组过滤、丢包率测量、时钟偏移影响的消除等几种网络测量中常用的关键技术。通过对这些关键技术的分析,探讨了各种测量模型以及存在的问题。由于网络快速发展,新应用不断提出,网络正变得越来越复杂。为了应付日益复杂的网络,必须提出新型的网络测量方案,为整个网络稳健、可靠、高效的运行提出重要依据。

Network Measurement and Its Key Technologies

Discuss the common methods,measurement parameters and key technologies in network measurement.Several common key technologies in network measurement,such as delay,packet losing,filtering out of "packet noise" and removal of clock skew,are iotroduced.Some measuring models and issues are discussed through the analysis of delay,packet losing,filtering out of "packet noise" and removal of clock skew.Because of the fast development of network and the continually advance of new applications,network is becoming more and more complex.In order to deal with the complex network,it is necessary to put forward new measurement models,which is important basis for moderate,reliably,effectively operating of network.
