Dual-machine hot standby method and system for rail transit multimedia system

Abstract

The invention discloses a dual-machine hot standby method and system for a rail transit multimedia system, and the method comprises the steps: configuring a first server and a second server, and assigning one server as a host and the other server as a standby; and the host and the standby machine receive data from an external network segment at the same time, so that the data of the host and the data of the standby machine are kept consistent. According to the method, data are received from an external network segment through a host and a standby at the same time. The data of the host machineand the data of the standby machine are kept consistent. The problem that the data synchronization workload in the dual-machine hot standby system of the rail transit multimedia system is large is solved, the host can rapidly switch services when faults occur, the overall stability of the dual-machine hot standby system of the rail transit multimedia system is improved, and the fault switching time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a dual-computer hot backup method and system for a rail transit multimedia system. Background technique [0002] The inventor found that the existing dual-machine hot backup solution requires two servers, one as the main machine and the other as the standby machine, each server uses its own disk to store business data, and the software is responsible for synchronizing the business data of the two servers in real time , the main machine serves the client and synchronizes business data to the standby machine in real time. Once the main machine fails, the business application is automatically switched to the standby machine to continue serving the client, protecting the business application from running as uninterrupted as possible. [0003] Because in the existing technical solution, the data of the main machine is synchronized to the standby machine in real time thro...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the first object of the present invention is to propose a dual-computer hot backup method for a rail transit multimedia system, through which the host computer and the backup computer simultaneously receive data from an external network segment, so that the host computer and the backup computer The data of the host machine is always consistent, which solves the problem of heavy data synchronization workload in the dual-machine hot backup scheme of the rail transit multimedia system. When the host fails, it can quickly switch services, which improves the dual-machine hot The overall stability of the backup system greatly shortens the failover time
