小卫星星座网络需要具有很好的容错抗毁能力,同时对于不同业务流能选择不同的优化路径进行传输。提出使用多拓扑路由技术解决小卫星星座网络的网络保护和流量优化传输问题。在STK和OPNET平台上设计了小卫星星座网络模型和多拓扑路由协议,并进行了仿真实验。仿真结果验证了星座网络的容错保护功能和对不同业务流的多路径路由选择功能。
The small satellite constellation network needs to have good fault-tolerant and anti-destruction capabilities, and at the same time, it can choose different optimal paths for different traffic flows for transmission. Proposed the use of multi-topology routing technology to solve the small satellite constellation network protection and traffic optimization transmission problems. The small satellite constellation network model and multi-topology routing protocol are designed on STK and OPNET platform, and the simulation experiments are carried out. Simulation results verify the fault tolerance of constellation network and multi-path routing functions for different traffic flows.
