| 摘 要： | 随着列车通信网络的不断发展,工业以太网已经成为当今主流的趋势.为了提高工业以太网的实时性,采用交换式工业以太网,并运用M/G/1排队模型分析不同优先级任务的时延特性；运用OPNET软件模拟构建列车网络拓扑结构,对列车传输信息划分优先等级进行传输,研究此优先级调度机制的可行性.

| Abstract: | With the development of train communication network, there is a main trend in using industrial Ethernet. In order to improve the network performance, switched industrial Ethernet is used with the M/G/1 queuing model to analyze the delays of different priorities of tasks. By using OPNET software, we set up industrial Ethernet topology model in train network to simulate network performance and verify the feasibility of this method. |
