Solution for QoS communication in China railway control and management system

With the rapid development of technology and advance of society, requirements for China railway control and management (CRCM) system have already reached a higher degree. Railway needs to improve its own competition ability by means of technical innovation, improvement of management and perfect service. Constituted by a series of subsystems, CRCM system is unwieldy and very complex. At present, these subsystems are independent each other and can not share information with each other efficiently, which affect the improvement of the CRCM system's efficiency, so it becomes very important to integrate these subsystems so as to improve railway's level of management and quality of service. This paper analyzes some technical problems that the integration CRCM system faced and present solutions for these problems, and put forward a heterogeneous system Qos communication solution based on structure of issue and order.
