| 摘 要： | 近年来，以太网在自动化行业得到了广泛应用，对其MAC层采用的CSMA／CD协议进行性能评价已成为必须。本文基于确定与随机Petri网(DSPN)对CSMA／CD进行了模型抽象，并且利用软件DSPNexpress-NG对该模型进行性能分析，所得结论对以太网组网有较好的参考价值。

| Abstract: | Recently, Ethernet has been applied to the automatic field extensively. It is indispensable to evaluate the CSMA/CD which is the protocol of Ethernet's MAC layer. A DSPN model for the CSMA/CD protocol is developed and run on the DSPNe- xpress-NG software system; two important performance measures, which are throughput and delay, are defined; DSPNexpress- NG then computes the results for these measures. Upon these results, detailed performance analysis is presented in this paper. |
