LEO卫星网络TCP拥塞控制算法改进研究
Research of TCP Congestion Control Algorithm over LEO Satellite Networks
【摘要】 基于Vegas拥塞控制算法提出了一个适合于LEO卫星网络环境的TCP拥塞控制算法(Vegas-AB),该算法是Vegas算法和Vegas-A算法的调和,可以动态地改变Alpha、Beta,Vegas-AB算法与Vegas-A算法的主要分支大体保持一致。在拥塞避免阶段,Vegas-AB算法更激进、更富有侵略性。仿真结果表明,在TCP吞吐量上,Vegas-AB算法优于Vegas算法和Vegas-A算法。
【Abstract】 Based on TCP Vegas congestion control algorithm, this paper presents Vegas-AB algorithmr. This algorithm can be fit for Iridium-similar LEO satellite networks. The improvement idea of Vegas-AB algorithm comes from Vegas and Vegas-A algorithms; it is the harmonization of two algorithms. The name of Vegas-AB means that this algorithm can change its parameters Alpha and Beta, and the main outline of Vegas-AB algorithm is still in accordance with Vegas-A algorithm. During congestion avoidance, the target of Vegas-AB algorithm, Vegas-AB algorithm is more radical and aggressive. Simulation results show that Vegas-AB algorithm is superior to Vegas and Vegas-A algorithms in throughput and round trip time.
