摘要
在距离矢量路由算法的基础上,对SpaceWire路由器的路由更新策略进行改进,引入链路状态路由算法。分析该算法的执行过程和Dijkstra算法的基本原理,完成运行该算法的路由选择模块设计,并借助网络模型对其进行仿真。验证结果表明,该模块能够自动获取当前网络状况信息,并据此计算新路由,改善SpaceWire网络的自适应性,从而提高SpaceWire网络的数据传输效率。
Based on distance vector routing algorithm,this paper improves the update strategy of SpaceWire router,and proposes the Link-State（L-S） route selection algorithm.By analyzing the executive process of L-S route selection algorithm and the principle of Dijkstra algorithm,it completes the design of routing module,and simulates the module by use of a simple network model.Verification result demonstrates that this module can get the information and recalculate new route information of current network automatically,improve the ability of self-adaptive of SpaceWire network and intensify the transmit efficiency as well.
