| Abstract: | 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. |
