| 摘 要： | 针对TCP Reno协议在HBDP网络中效率低下的问题,提出用并行TCP高速协议来提高TCP在网络中的性能.通过修改NS2 TCP-Linux中自带的协议源代码,实现了并行TCP协议,并构建HBDP网络模型对其性能从吞吐量、丢包率、文件传输应用的时间3个方面进行了仿真.实验结果表明,并行TCP协议在没有增加丢包率的前提下,可以获得更高的吞吐量和更短的文件传输时间,能够满足HBDP网络的传输要求.

| Abstract: | Parallel TCP has been proposed to improve TCP performance due to TCP Reno performs inefficiently in HBDP networks.Parallel TCP protocol has been achieved through modifying the source code in NS2 TCP-Linux.Throughput,packet loss rate and the time of file transfer have been simulated through building the model of HBDP networks.Experimental results show that better throughput and shorter time of file transfer are obtained in parallel TCP on the condition that packed loss rate is not increased.Parallel TCP can meet the needs of HBDP networks. |
