基于SDN的铁路通信传输系统仿真平台研究
Research on Simulation Platform for Railway Transmission System Based on SDN
摘要
Abstract
The transmission system is a main component of the railway communication system,providing channels for all railway service networks.However,due to its characteristics of large size,high price,and complex operation,the transmission equipment is not suitable for large-scale application in laboratory environments.On the basis of in-depth research on the main functions of the railway transmission system,the functional requirements of its simulation platform are proposed,including the normal telegram transmission functions and various network fault scenarios.Then,the characteristics of the SDN architecture are utilized,such as separation of forward and control,and provision of open and programmable interfaces.On this basis,the architecture design of the transmission system simulation platform based on the SDN technology is presented,and the detailed process design for different functional requirements is provided.At present,the results of this study have been applied in the testing environments of multiple projects.关键词
