Abstract

The present invention provides a method and system for processing train communication network data. The method includes: running the link state protocol of the multi-link transparent interconnection TRILL protocol, and the protocol message of the link state protocol carries the at least three backbone network The neighbor direction of the node during the neighbor interaction process; determine the position sequence relationship of the at least three backbone network nodes according to the neighbor directions of the at least three backbone network nodes and the directions of the ports of the at least three backbone network nodes; The position sequence relationship of the at least three backbone network nodes is to assign a backbone network node identification number to the at least three backbone network nodes; according to the backbone network node identification numbers of the at least three backbone network nodes and access to the at least three backbone network nodes forward the data from the source terminal device to the destination terminal device.

Description

technical field [0001] The invention relates to the technical field of train network communication, in particular to a data processing method and system for a train communication network. Background technique [0002] Due to the substantial increase in train speed, the gradual complexity of the train network structure, and the continuous increase of new large-capacity services, in order to meet the requirements of the train communication network for important performance such as bandwidth, real-time, and reliability, the train communication based on industrial Ethernet The network has become the new development direction of the train communication network for the International Electrotechnical Commission and many developed countries. [0003] In the prior art, an Ethernet-based train communication network is defined based on the International Electrotechnical Commission (International Electrotechnical Commission, IEC-61375-2-5) standard. The IEC-61375-2-5 standard defines a...
