| 摘 要： | 网络层处于空间信息传输协议体系的关键层,其协议选择关系着能否实现未来航天任务提出的动态数据传输、灵活路由选择、与地面网络的互操作性等技术要求。对CCSDS空间分包协议、SCPS-NP协议和IP协议等可用于空间通信的网络层协议进行了总结分析,并从功能、地址空间、协议开销和技术成熟度及产品支持等方面进行了比较。可以看出,IP协议是未来空间任务的合理选择。对于没有空间链路路由选择的任务,可先使用CCSDS空间分包协议解决动态数据传输问题。

| Abstract: | The increasing of space explorations requires space communication protocols to provide more capabilities,such as adaptive data transformation,dynamic routing,and easy interoperability between the ground system and spacecraft.Network Layer is the key protocol layer to satisfy above technical requirements.An in-depth analysis of CCSDS space packet protocol,SCPS-NP and IP is made in this paper.Compare is made in items of function,address space,overhead and COTS support.It is derived that IP is a reasonable solution for future space missions.For missions that don't need routing in space link,CCSDS space packet protocol could be adopted to achieve adaptive data transformation. |
