摘要： 研究了类Iridium系统的LEO卫星网络环境下各种TCP(TransmissionControlProticol)拥塞控制算法的性能表现,包括Reno,Newreno,SACK,Vegas四个算法,侧重点是各种性能参数在整个网络上总的平均结果,关心网络的整体性能·仿真结果表明在平均往返时延上Vegas算法优于其他算法,但各种算法在平均吞吐量方面的差别并不明显·与单一链路的仿真结果比较,使用完整的网络进行仿真具有积极的意义·

关键词: LEO卫星网络, TCP, 拥塞控制, 平均吞吐量, 平均往返时延

Abstract: The performance of TCP (Transmission Control Protocol) congestion control algorithms over Iridium-like LEO (Low Earth Orbit) satellite networks is analyzed, including Reno, Newreno, SACK and Vegas algorithms. The focuses are on the whole network performance of various parameters and the average numerical value. The result of simulation shows that the Vegas algorithm is superior to other algorithms in average RTT, though there are no obvious differences among the four algorithms in the average throughput. By comparison with the result of simulation of single link, using the complete network topology to simulate TCP congestion control algorithms is more positive.
