摘　　要：空间通信的发展趋势是从定制、专用和非标准的遥测遥控系统向通用、开放、标准化和网络化的空间互联网方向发展。早期的空间通信系统为项目定制开发，独立使用，标准化程度低。由于空间通信环境条件的特殊性，为适应端到端时延、通信链路非对称、数据丢包率等不利因素，空间通信协议进行了有针对性的增强和适配。文中研究了空间互联网的协议体系，对比地面互联网分析了其主要协议的区别和不同，并对协议体系向天地一体化发展和演进的技术途径进行了展望和预测。Space communication is evolving from private systems for telemetry and telecomm toward space internet with general purposes, better standardization and openness. At the initial stage, space communica- tion systems were tailored for particular users and not standardized. Because of the particular circum- stance, the protocols of space communication were improved to adapt to disadvantageous conditions, such as end-to-end delay, asymmetric communication link and data packet loss. This paper studies the protocol stack of space internet and analyses the protocols in comparison with TCP/IP protocols , and prospects its evolution toward integration between space and earth.
