摘　　要：随着高速网络测量研究内容的扩展,网络测量设施在提高性能的同时须支持测量的可扩展性以适应不同网络环境和添加新测量研究的需要。针对已有网络测量软件可扩展性的不足,分析了高速多链路逻辑信道的特点及对被动测量方式的影响,设计和实现了一套适用于高速网络环境的可扩展被动流量测量平台系统。该系统基于多机协同数据流模型,采用分层耦合设计结构、对象化抽象和XML格式的交互描述,支持对高速多链路逻辑信道测量与新测量功能的可扩展性。As the expanding of high- speed network measurement research, network measurement infrastructure, besides performance improvement,should provide expansibility to support kinds of high network link types and new measurement needs. However the existing software- based network measurement methods today are short of expansibility and unfit for the high - speed network measurement. Based on the analysis of the multi - link logic channel, a typical kind of high- speed network connection, and its impact on passive measurement methodology, this paper gives out an expansible high- speed network traffic passive measurement platform. This platform＇s design uses data flow model of multi- processor system, layered coupling framework,object- oriented abstraction and XML formatted intercommunication to make it much easier to support high speed multi- link logic channel measurement, and to add new measuring function when needed.
