当前空间通信的发展趋势是空间通信网与地面通信网融合,建立天地一体化的信息传输系统。针对天地一体化信息传输系统中IP over CCSDS网关中的协议转换技术开展研究,参考了IP over CCSDS Space Links等相关建议,在Linux内核的网络协议栈中实现了IP协议与CCSDS AOS空间数据链路协议的相互转换,并通过试验对在CCSDS-AOS空间数据链路之上进行IP传输进行了测试与验证,表明了利用IP over CCSDS网关构建天地一体化信息传输系统的可行性,并给出了工程应用的实现建议。
The current development trend of space communications is the integration of space communications network and terrestrial communications network, the establishment of world-integrated information transmission system. Aiming at the protocol conversion technology in IP over CCSDS gateway in TIC, a reference is made to related suggestions such as IP over CCSDS Space Links. IP protocol and CCSDS AOS spatial data link are implemented in the network protocol stack of Linux kernel. Protocol conversion, and tested and verified the IP transmission over the CCSDS-AOS spatial data link by experiment, which shows the feasibility of using IP over CCSDS gateway to build a unified world-wide information transmission system. Engineering application of the recommendations.
