摘　　要：基于星上处理的多星IP组网是天地一体化网络关键技术。针对星载硬件平台处理能力不足的现状,提出了一种地面IP路由、星上标识交换和星间标识转发的多星路由交换架构,设计了专用的卫星路由协议和星上数据标识交换。利用OPNET仿真软件搭建了基于星上处理的多星组网网络模型,对星地协同的路由控制和路由标识交换进行仿真,仿真结果表明,基于地面IP路由、星上标识交换和星间标识转发的路由交换架构,可减少路由协议开销,提高网络收敛速度,满足多星IP组网应用。The multi-satellite IP network based on on-board processing is one of key technologies for earth integrated network. Considering limited processing capability of satellite hardware platform, this paper proposes an multi-satellite routing and switching architecture for ground IP routing,on-board identifier-based switching and inter-satellite identifier-based forwarding.The private satellite routing protocol and on-board identifier-based switching process are given. The OPNET simulation software is used to build Multi-satellite Network model. The simulation of routing control and identifier-based switching based on satellite-ground coordination is implemented,The simulation results show that multi-satellite routing and switching architecture have lower bandwidth overhead and higher routing convergence performance,and can be used in multi-satellite IP network.
