Abstract: The integration of data communication network and computer network plays a crucial role in promoting the level of railway network resource utilization and the application system of information based construction. In order to ensure the stability, reliability and maintainability of the integrated network, based on the analysis of the existing railway network on the two railway network integration scheme,combined with the technology application status and development trend, the feasibility of applying virtualization in the two railway network integration scheme was discussed. The analysis proved that the virtualization technology could fully meet the requirements of China Railway, and achieved good application effect in the actual railway scene.
