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.
