摘要
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。
Fault-tolerance and optimization in path selection for various traffic flows are essential for small satellite constellation network.Multi-topology routing is proposed to address the issues of fault-tolerance and traffic optimization.The simulation model for small satellite constellation network and the multi-topology routing protocol are designed with STK and OPNET,the simulation experiment on the fault-tolerance and resilience of multi-topology routing algorithm also done,and various optimal routes based on different topologies could be selected for various traffic flows.
