摘　　要：探讨了为适应空间网络环境对TCP协议机制进行的一些改进，通过模拟实验，对协议改进方案的性能进行了分析和比较。实验结果表明：协议改进后能够减小时延，避免不必要的重传，提高了信道的利用率。Attempts have been made to improve the TCP protocol mechanism to adapt it to the space network environment. The performance of the protocol improvement scheme is analyzed and compared through simulation and experiments. The results show that the improved TCP protocols reduce communication latency time and prevent unnecessary retransmissions. As a result, it significantly improves link utilization.
