Abstract：Thesatelitecommunicationnetwork hasthecharacteristicsoflongdelay，highbiterrorrateandbandwidth asymmetry，which leads tothereductionofbandwidthutilizationandservicequalityof traditional groundcongestioncontrol algorithminsatelltenetwork.Asateliecommunicationcongestioncontrolalgorithmbasedonte Vegasalgorithmoptimization is proposed.BasedonthenewRTTcalculation method，thisalgorithmcannotonlyavoidthe wasteofforwardlink bandwidth duetothereductionoftransmissionrate whenthereverselinkisongestedbutalsodnamicallyadjusttheelevantpraeters of the congestionavoidance phase，making the adjustmentof the CWND more reasonable.By optimizing the congestion avoidance phaseof Vegas algorithm， the maximization of algorithm performance is sought.The experimental results show that the proposed algorithm in this paper improves the throughput and bandwidth utilization ofsatelitecommunication networks.
