摘要

建设天地一体化网络是中国的一项重要工程。在空间网络中引入IP协议族及相关路由技术能充分发挥互联网的长处，更加快速和高效地实现多网融合。然而，空间网络的特殊性使得传统互联网的路由技术不能直接被使用。该文提出一种基于传统域内路由协议OSPF的天地一体化网络域内路由协议OSPF+，利用卫星运动轨迹可以预先计算的规律，引入拓扑预测，结合扩展的邻居状态机来优化链路状态数据库的同步，在空间网络自治系统中实现低开销、高稳定性的自适应动态路由。模拟实验结果表明：OSPF+能在约1 s的时间内快速完成路由收敛，且达到98%以上的稳定性。

Abstract

Constructing an integrated terrestrial and space network is one of the key projects in China. Heterogeneous networks can be efficiently integrated using the IP protocol family in space networks to leverage the advantages of the Internet. However, traditional routing techniques cannot be used directly due to the special characteristics of space networks. This paper describes an extended traditional intra-domain routing protocol based on OSPF for network communications in space. The protocol uses topology predictions based on the regular motion of satellites and extends the neighbor state machine to optimize the synchronization of link-state databases to achieve efficient, stable dynamic self-adaptive routing. Simulations show that this protocol has a convergence time of less than 1 second and greater than 98% stability.
