信息交互式列车骨干以太网链路管理的实现

Implementation of link management for Ethernet train backbone network based on information exchange

为了能准确判断链路状态,文章提出了一种基于列车拓扑发现协议报文的链路管理方法,详细阐述了该协议的实现过程与方法,以及基于该列车拓扑发现协议报文的链路管理功能及其运行过程,并通过试验验证了相关链路管理功能。

In order to accurately judge the link status,this paper proposes a link management method based on train topology discovery protocol message.It describes the realization process and method of the TTDP,also the function and operation process of link management based on TTDP message in detail.The related link management functions are verified by experiments.
