摘要

本文通过仿真研究了不同类型的TCP拥塞避免算法在卫星链路上的性能。假设地球同步轨道卫星。为了更好地理解，首先讨论地面网络上的TCP。然后，在卫星链路上的TCP情况下，采用具有不同通告窗口大小的TCP来观察每个TCP拥塞避免算法的行为。我们的结果表明，SACK明显优于其他拥塞避免方案。对于卫星上的TCP SACK，通告窗口的大小对其性能影响很大，特别是当窗口大小超过TCP标准窗口大小时。

TCP over satellite link with SACK enhancement

This paper uses simulations to study how different kinds of TCP congestion avoidance algorithms behave on the satellite link. A GEO satellite is assumed. For better understanding, TCP over a terrestrial network is first discussed. Then, in the case of TCP over a satellite link, TCP with varying advertised window (awnd) size is employed to observe the behavior of each TCP congestion avoidance algorithm. Our results reveal that SACK outperforms the other congestion avoidance schemes significantly. For the case of TCP SACK over satellite, the size of the advertised window greatly affects its performance, especially when the window size exceeds the TCP standard window size.
