摘要

由于列车拓扑发现协议TTDP（Train Topology Discovery Protocol）自身机制，在列车初运行禁止状态下，网络节点不能满足所有故障恢复场景的应用需求，包括多个中间节点丢失或多个丢失的相邻节点中包含1个端节点的多节点故障恢复应用场景。因此，文章设计了一种新的节点故障恢复方法来解决该问题，并实现与标准TTDP协议的完全兼容。通过增加独立供电的特殊存储单元来实现对网络配置信息的存储；通过设立节点的故障预备（初始化时将网络配置信息写入特殊存储单元）、识别（进行相邻节点拓扑计数值匹配）、恢复（调用特殊存储单元的网络配置信息）流程，对节点设备进行改进，实现了以太网列车骨干网ETB（Ethernet Train Backbone）节点在特殊场景下的故障恢复。针对本文提出的故障恢复方案，通过模拟测试的方式进行了验证，确认了方法的有效性和可行性。

Abstract

Due to the mechanism of the TTDP (Train Topology Discovery Protocol)

network nodes cannot meet the application requirements of all fault recovery scenarios in the status of inauguration inhibition

including multi-node fault recovery scenarios when multiple intermediate nodes are lost or one end node is included in multiple lost adjacent nodes. Therefore

in this paper

a new node fault recovery method was designed to solve this problem and achieve full compatibility with the standard TTDP. The storage of network configuration information was realized by adding a special storage unit with an independent power supply. The node equipment was improved by setting up the node fault preparation (writing the network configuration information to the special storage unit during the initialization)

identification (matching the topology count values of adjacent nodes)

and recovery (calling the network configuration information of the special storage unit) processes

so as to realize the fault recovery of the Ethernet train backbone (ETB) node in the special scenario. The proposed fault recovery scheme was verified by simulation test

which confirms the effectiveness and feasibility of the method.
