网络流量测量是网络管理的基础之一,流量测量体系结构的研究是网络流量测量及其应用的基础和重要环节。对传统的网络流量测量方法的特点进行了分析,对高速网络流量测量中的关键问题进行了研究,采用数据流归并技术,以提高实用性为目的,在Linux平台和开源软件的基础上提出了一种新型的基于分布式探针的高速IP网络流量测量体系,并对其构成及特点进行了分析。该测量体系提供了实用的高速测量平台和数据分析接口,具有广阔的应用前景。

Network traffic measurement is a fundamental work in network management, while research on measurement architecture is regarded as a base and an important approach. The characteristics of traditional traffic measurement methods are analyzed, primary problems in traffic measurement of high-speed network are investigated. To prove its practicability, with the flow-mergence method adopted, a new traffic measurement architecture based on distributed probes for high-speed IP network is proposed which is developed based on Linux and open-source software. Its framework, characteristics and merits are also analyzed. The architecture provided an applied platform and an analysis interface for high-speed traffic measurement. We believe there is a nice future in its application.
