摘　　要：拓扑结构优化模型是网络中的一类重要模型,可以有效地优化系统整体链路性能。针对电磁发射系统以太网拓扑结构中部分节点和链路的负载过大,一旦发生堵塞,将会影响网络中关键链路性能的问题,建立网络拓扑结构优化的多目标规划模型,并提出一套基于基因环操作的遗传算法对其进行求解,通过仿真得出最优的网络拓扑结构。根据仿真结果修改实际网络节点默认配置参数,结果显示该模型和算法能有效均衡负载,降低网络冲突率,且不需要改变电磁发射系统以太网的物理链路,不会增加额外成本,对电磁发射类系统具有普适性的意义。The optimization model of topology is a kind of important model in network,which can effectively optimize the overall link performance of the system.In Ethernet topology of electromagnetic launch system,some nodes and links are overloaded,once the blockage occurred,the performance of the key links in the network can be affected.To solve this problem,a multi-objective programming model for optimizing Ethernet topology was established and the genetic algorithm based on genetic ring operation was designed to solve the model.The simulation was carried out to obtain the optimal Ethernet topology.Default parameters of corresponding network nodes in the practical system were modified through simulation and calculation.The result shows that the model and the algorithm can effectively balance load,reduce conflict rate and optimize the topology without changing the physical link by adding cost,which is of universal significance to electromagnetic launch system.
