Abstract: With the gradual advancement of the efforts to develop China’s transport strength, higher requirements have been put forward for the IT transformation of urban rail transit laboratories. Based on the technical framework of cloud computing, this paper proposes a scheme of shared cloud platform for testing, and builds an innovative new-generation laboratory for urban rail transit signaling in cloud environment. Thanks to the application of the VLAN and routing based communication technologies, partial coupled linkage can be achieved among the public cloud, the private cloud and the laboratory area. However, due to the limits on communication links of the public cloud, communication cannot be achieved with other areas within different network segments. Thanks to the innovative application of the VXLAN technology and the establishment of the layer-two communication tunnel, the needs for communication within the same network segment are addressed, so that more test scenarios can be established. The resulting hybrid cloud platform expands the business scope of and supports the digital transformation and intelligentization of urban rail transit laboratories.
