摘要
针对卫星星内和星间一体化组网问题,结合已有的智能化航天器综合电子系统协议体系架构,提出了基于IPv6和空间包协议的空间路由策略。该策略借鉴IPv4和IPv6的隧道机制,利用空间包局部信息与IPv6全局信息的映射完成协议封装。以星载路由器为核心搭建演示验证系统,通过典型实例验证该策略具有一体化组网的可行性。在分析策略存在的灵活性问题基础上,提出了定制空间包格式、修改协议信息表的优化措施。该策略的设计与其在星载路由器中的实现,可为我国天地一体化信息网络的构建提供参考。
Aiming at the problem of intra-satellite and inter-satellite integrated network, a strategy of space routing based on IPv6 and SPP (space packet protocol) is proposed, according to the existing protocol architecture of intelligent spacecraft avionics system. The thought of tunnel schema between IPv4 and IPv6 is learnt and the map between local information of SPP and global information of IPv6 is used to accomplish protocol encapsulation. A demonstration and verification system has been constructed with onboard router as the core and a typical case has been designed to verify the integrated network feasibility of the strategy. An optimized measure, customizing space packet format and modifying protocol information map, has been proposed, based on the existing flexibility of the strategy. The design and realization of the strategy within onboard router supplies the idea for constructing integrated space-ground network and establishes a technical foundation for building satellite network in the future.
