摘　　要：卫星网与IP网的结合是当今卫星通信领域最热门的话题之一。由于卫星信道具有高误码率、长时延以及上下行链路的非对称性等,导致卫星IP网络通信效率的降低。在简要介绍了目前主流的TCP加速技术的基础上,重点研究海事卫星第四代通信网络系统以及海事四代系统采用的通信加速方案,并应用国产BGAN终端进行了TCP通信性能实验和验证。实验结果表明,使用TCP加速算法能大大提高卫星通信效率。该研究结果为我国自主宽带卫星通信系统通信加速技术的设计和应用提供了参考。The combination of satellite network with IP network is one of the most popular topics in the field of satellite communication,and the satellite channel has characteristics of high error rate,long delay and uplink/downlink asymmetry,which lead to the decrease of IP satellite network communication efficiency.This paper briefly introduces the current mainstream TCP acceleration technology,and the research is focused on the communication acceleration program adopted by the 4th-generation maritime satellite communication network system and maritime 4th-generation system.The domestic BGAN terminal is applied to TCP communication performance test and verification,and the experimental results indicate that the TCP acceleration algorithm can improve satellite communication efficiency,the research results can provide certain reference for China’s design and application of independent broadband satellite communication system acceleration technology.
