利用随机Ｐｅｔｒｉ网对一种高性能的分布式路由体系结构进行了模型抽象、化简和性能分析．为解决模块数增多而引起的状态爆炸问题，提出了一种分割迭代的简化分析计算方法，从而大大降低计算的复杂性．最后，给出了计算比较结果，显示了这种算法的可行性和有效性． Using a stochastic Petri nets, a high performance distributed routing architecture is modeled abstraction, simplification and performance analysis. To solve the problem of state explosion caused by an increase in the number of modules, a simplified analysis and calculation method of segmentation iteration is proposed, which can greatly reduce the computational complexity. Finally, the result of calculation and comparison is given, which shows the feasibility and effectiveness of this algorithm.
