摘要

在ETB/ECN列车通信网络中，列车重联或解编时，其设备的列车级IP地址会随重联车ETB属性和重联方向的不同而改变，网络技术人员需要利用ETB初运行结果对列车级IP地址重新进行计算，这样不利于效率的提高。文章提出了基于URI域名的寻址方案，相比常用的IP寻址方案，URI地址可根据其所处列车位置、车辆位置和设备功能来确定，不随列车拓扑变化，源端设备通过静态的URI地址与域名服务器交互后就可得到目的设备列车级IP地址，完成ETB通信。URI寻址降低了网络系统设计过程中动态IP寻址的复杂度，解决了WTB/MVB网络无法对全列车进行单点维护的问题，提升了网络开发和维护效率。

Abstract

In the ETB/ECN train communication network, when the train coupling or de-coupling, the train-level IP address of its equipment will change with the ETB attribute and coupling direction of vehicles. The network technician needs to use the ETB inauguration result to calculate the train-level IP address, which will reduce the development efficiency. An addressing scheme based on URI domain names was proposed. Compared with commonly used IP addressing, the URI address of a device was determined by its train location, vehicle location and device function, which did not change with the train topology. After the source device interacted with the domain name server through the static URI address, the train-level IP address of the destination device was obtained to complete the ETB communication. URI addressing reduced the complexity of dynamic IP addressing in the network system design process, and solved the problem that WTB/MVB networks could not maintain the entire train at a single point, which improved the efficiency of network development and maintenance.
