摘　　要：路由架构及协议是GEO卫星IP网络技术体制设计的重要内容。针对星载硬件平台处理能力受限无法满足大规模地面终端组网的现状,提出了一种星上OSPF路由、终端RIP路由和星地隔离的路由架构及协议部署,设计了星上OSPF路由计算优化方法和终端RIP路由信息跨星洪泛机制。该方法中星载路由器不再参与地面终端路由计算,降低了星上协议处理压力。OPNET仿真结果表明,在星地路由隔离条件下,终端RIP路由仍能正常收敛,从而满足GEO卫星IP网络大规模组网应用。In GEO satellite IP network,routing architecture and protocol is an important component of traditional system.Limited processing capability of satellite hardware platform can not satisfy network requirements for the large-scale Terminals.This paper proposes a satellite-ground isolation routing architecture for satellite OSPF routing protocol and terminal RIP routing protocol.Optimization method of satellite OSPF and inter-satellite flooding mechanism of terminal RIP are given.In this approach,space router will not deal with terminal RIP packet,reducing the burden of onboard processing.Simulation show that the terminal RIP can run regularly under the condition of satellite-ground isolation,which can be used in GEO satellite IP network.
