摘　　要：针对告警直传系统的事件漏发及重发问题,本文提出了一种基于ICE对等模式的双机同步方法。本文分析了事件漏发及重发问题的原因,设计了一种以事件特征值和主站IP地址作为事件惟一标识的同步数据结构,采用该同步数据和ICE对等模式的双机同步方法,实现了告警直传双机切换过程中减少重发、杜绝漏发事件的目标,保障了告警直传双机切换过程中双机数据一致性。通过仿真试验,验证了该同步方法和数据结构的有效性。A dual machine synchronization method based on peer-to-peer mode of ICE is proposed,which solves the problem of event leakage and retransmission in alarm transmission system.The reason of missing and retransmitting event is analyzed,and the synchronous data structure with the event eigenvalue and the IP address of the master station as the unique identification of event is designed in the paper.The synchronous data structure and dual machine synchronization method of ICE peer-to-peer mode is used to realize the goal of avoiding retransmission and eliminating leakage events in the dual machine switching process of alarm transmission,which ensures the data consistency of alarm transmission in the process of dual machine switching.The validity of the synchronization method and data structure is verified by simulation experiments.
