摘　　要：新的传输控制协议不断涌现,迫切需要一个系统的评价体系。提出了一个系统的和可重复的评价方法,定义了一系列性能测度集和仿真用例,基于NS2对最近几年提出的几个具有代表性的高速长距离网络中TCP协议High-Speed TCP、Scalable-TCP、FAST-TCP、BIC-TCP以及H-TCP的性能进行了比较和评价。仿真结果表明,通过一致的应用性能测度和标准仿真用例可以获得有价值的结论。Recently, there are some new transmission control protocols for high speed long distance networks have been presented, so a real need has developed for systematic evaluation architecture. In this paper we present a systematic and repeatable evaluation manner, and a serials of performance metrics and simulation benchmark were defined. The NS2-based simulation experimental results evaluating the performance of the High-Speed TCP, Scalable-TCP, FAST TCP BIC-TCP, and H-TCP proposals were presented. The results demonstrate that consistent application of performance metrics and standardized simulation benchmark can yield results of considerable value.
