摘要
列车级以太网设备ETBN(Ethernet Train Backbone Node)是列车级以太网的核心设备。研究了列车级以太网拓扑发现协议TTDP(Train Topology Discovery Protocol)在ETBN中实现的方式,在列车级线型拓扑中研究列车以太网数据传输的特点,对TTDP报文内容、发送周期等参数进行合理的设置。试验结果表明所开发的ETBN设备能够响应列车级拓扑变化,同时具备良好的列车级数据传输能力。
The Ethernet Train Backbone Node （ETBN） is the key device which is used in the Ethernet Train Backbone （ETB）. Our research focuses on the implementation of the Train Topology Discovery Protocol （TTDP） in ETBN. Based on the features of the line topology in ETB, the mechanism of ETB-level information exchange is discussed. The details with TTDP message content and transmission parameters have been designed. The results show that the well-designed ETBN can automatically configure the network parameters to response the ETB-level topology changes. Moreover, the results also demonstrate that the proposed ETBN has good capacity for the ETB-level data transmission.
