摘　　要：在卫星组网过程中,IP语义过载不仅引起星载路由器的路由表急剧膨胀,而且还导致卫星网对移动终端的限制。在基于标识/位置分离思想的卫星网路由架构下,卫星终端通过引用2个命名空间分别表示终端的位置和标识,利用地址映射系统实现不同空间地址的映射解析,达到卫星网络和用户网络分离的目的。卫星网路由架构采用OPNET进行仿真建模,结果验证了该架构有效地解决了卫星网路由的扩展性和终端的移动性。In the satellite network,the IP semantic overload can lead to rapid expansion of the routing table and restrictions to the terminal.In the satellite network routing infrastructure based on the thought of identity and location separation,the satellite terminals refer to two address spaces to figure identity and location and use the address mapping system to map and resolve different network addresses to separate satellite network and user network.The satellite network routing infrastructure uses OPNET modeling and simula-tion,and the results show that the routing infrastructure can improve the scalability of the satellite backbone network and mobility of terminals.
