【摘要】 ARCNET网络的建模与仿真不仅能对ARCNET网络性能进行评估,而且能优化ARCNET网络设计。在深入理解ARCNET协议的基础上,利用OPNET网络仿真软件建立ARCNET列车通信网络的网络拓扑结构模型、节点的应用层进程模型和链路层进程模型。利用该模型,对ARCNET列车通信网络进行实时性和吞吐量的仿真。通过仿真得出要保证系统正常运行的最大误码率和影响端到端延时的主要因素。更多还原

【Abstract】 Modeling and Simulation of ARCNET network was used to evaluate ARCNET network and optimize the ARCNET network design. On the basis of in-depth understanding of ARCNET protocol, it was utilized OPNET network simulation software to build the ARCNET train communication network, included the topology model, the node application layer model and the link layer model. The real-time performance and throughput capacity for the ARCNET train communication network were analyzed using the model. The simulation results showed that the main factors which influenced the end to end delay time, the BER(bit error rate) to guarantee the normal running of the System were given.更多还原
