网络流量测量技术分析

An analysis of traffic measurement technology

网络流量测量技术是用于分析网络状况、掌握流量特性的有效方法.首先分析了在进行网络流量测量时需要主要考虑的端点、方向、时间粒度和协议层次四个因素,然后重点对已有的网络流量测量技术进行分类和总结.

Network traffic measurement technology is an effective way of analyzing net condition and understanfing traffic features. A new definition of network flow is proposed based on the analysis of four flow factors, which are endpoints, directionality, time granularity and protocol layer. Then, the existing traffic measurement technologies and types are summarized and analyzed, which is the emphasis of this paper.
