- Abstract
To further improve the system performance of railway vital signaling data networks, this paper analyzes the existing in-band network management system and its problems based on an analysis of the existing management system for vital signaling networks. Then, it proposes an optimization scheme of the grid structure for in-band network management system and the time synchronization of NMS and CTC. Moreover, it points out that the out-of-band network management system can be introduced into the current railway network management system, and that the optimization scheme can be achieved through the cooperation of the in-band and out-of-band systems. This research can provide reference for further improving the reliability of the network management system for railway vital signaling data networks in China.
