【摘要】 为了改善交换式工业以太网的网络性能,给出了其采用环形拓扑时的设计原则,并把它们等价为一个带约束条件的网络优化问题．然后通过设计遗传算法来寻找该优化问题的解,为避免遗传算法的早熟收敛,在进化过程中采用了基于混沌迁移的伪并行进化方案．最后针对一个仿真例子,对比了基于遗传算法进行拓扑优化前后的网络性能,仿真结果验证了该优化方法的有效性．更多还原

【Abstract】 To improve the network performance of switched industrial Ethernet, the design principles are given when a ring topology is used. The design principles are equivalent to a network optimization problem with constraints. Then, a genetic algorithm is designed to search solution for this optimization problem, and the chaotic migration-based pseudo-parallel evolution strategy is employed to prevent the premature of genetic algorithm. Finally, a simulation is carried out to compare the network performance before and after topology optimization, and the simulation result validates the effectiveness of the proposed optimization method.更多还原
