摘　　要：为进一步提高铁路信号安全数据网系统性能,在分析现有信号安全网络管理系统的基础上,对现有带内网管系统及其存在的问题进行分析。提出对带内网管网格结构和NMS和CTC时间同步的优化方案,并指出在当前铁路网管系统中引入带外网管系统,通过带内外系统协同作用的优化方案。为进一步提高国内铁路信号安全数据网络管理系统的可靠性提供参考。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.
