摘　　要：对于采用星间链路的低轨卫星星座,IP的双重属性导致了星载路由表的过载,并且难以融合解决低轨卫星网络移动切换问题。基于名址分离的思想,采用双层路由架构,设计映射服务器的部署方式及多个名字空间,提高低轨卫星网络的灵活性及扩展性,并且通过引入链路层切换信息,解决低轨卫星面临的无缝切换难题。For LEO satellite constellation using inter-satellite links,the dual nature of IP causes the overload of the on-board routing table,and it is difficult to converge to solve the problem of mobile handover of the LEO satellite network.Based on the idea of locator identify separation,a two-layer routing architecture is adopted to design the deployment mode of the mapping server and multiple name spaces,thus to improve the flexibility and scalability of the LEO satellite network,and by introducing link layer switching information,to solve the seamless switching problem faced by the LEO satellite.
