Windows下包对算法的设计和实现

Design and Implementation of Packet Pair in Windows System

分析了包对算法,讨论了包对算法对时钟精度的要求以及windows下包对算法的时钟选择方案,实现了采用高精度运行计数器计算时钟的包对算法。实现结果表明,这种方法能有效准确地实现网络带宽的测量。

This paper analyses the packet pair bandwidth measurement algorithm,then discusses the requirement of it to clock precision and the schemes of clock selection in Windows system.Finally,it implements the algorithm by adopting thigh-resolution performance counter as the clock scheme.The experiment results show that from this scheme ,people can measure network bandwidth efficiently and precisely.
