互联网应用性能测量系统的研究与实现

致力于建立互联网应用网络性能的基础性测量平台，它为互联网上众多的应用系统提供了一个分布式可扩展的性能测量系统，首先分析了应用系统性能数据的数据特征，并将性能数据划分为3类数据集，建立了互联网应用系统网络性能测量模型，并针对应用网络性能测量数据获取的难点，提出了应用探针和区域探针的分布式体系结构，最后结合海量信息系统测量平台的研究，给出了该模型的具体实现技术。

Research and Implementation of Network Performance Mesurement of Internet Applications

Emphasis is put on how to build a measurement infrastructure for network performance of Internet applications The infrastructure supplies to the numerous increasing Internet applications a scalable performance measurement system In this paper, the performance data are first characterized and categorized into three types Then a scalable performance measurement model is built In this model a distributed architecture is designed, which is composed of application-specific collectors and regional collectors Finally, the architecture and technologies are discussed as an implementation of the model in the project of the national key basic research project "Theoretical and Experimental Studies on Applications Based on the Nationwide Information Infrastructure
