摘　　要：基于空间站与地面站之间的通信特点及其对于TCP传输性能的影响,在充分利用空间通信链路的基础上,提出了一个适合于空间站通信环境的基于TCP分段思想的SCPS-TP协议转换网关,详细讨论了协议转换网关的设计思想和实现方案,并对协议转换网关的进行了性能测试。Considering the inherent features of communications between space station and ground stations, and with regard to their influence on the performance of traditional TCP, a SCPS-TP protocol converter based on Split-TCP is proposed to accommodate the space station＇s communication environment. The design and implementation approaches of the protocol converter are discussed in detail, and the performance of the converter is tested.
