Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] The embodiment of the present invention provides a dual-machine hot redundancy backup method, such as figure 2 shown, including:

[0035] 201: The second server, which is the default slave device, monitors the working status of the dual-machine hot redundancy backup through the heartbeat packet channel with the first server that defaults to the master device;

[0036] Preferably, the monitoring of the working state of the dual-mac...

Abstract

An embodiment of the invention discloses a dual-computer hot redundancy back-up method and a dual-computer hot redundancy back-up system. The dual-computer hot redundancy back-up method comprises the steps: a second server defaulted as a slave device monitors the working state of dual-computer hot redundancy back up through a heartbeat package channel between the second server and a first server defaulted as a main device; and if the working state is stoppage, the second server is shifted to be the main device. The hardware configuration is simple, and the network transmission flow can be decreased only through one heartbeat package channel. In the embodiment scheme, one device is defaulted as the main device, and the other device is defaulted as the slave device. When the main device breaks down, the time interval of fault detection is short, the efficiency is high, and compared with about 10 seconds by means of the existing technical scheme, the fault detection work only needs about 3 seconds by means of the method.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a dual-machine hot redundancy backup method and system. Background technique [0002] In today's large-scale projects, especially some high-end users, such as electric power, subway, public security and other industries, software and hardware are required to have zero failures and run 7X24 hours. Therefore, the reliability of software and hardware has always been the focus of users' attention. In order to improve reliability, software and hardware redundancy backup has always been the preferred solution for large-scale projects to ensure reliability. This solution is based on the user's requirement that the software and hardware run for a long time without failure. Even if there is a failure, it must be able to quickly switch between the master and slave devices to minimize the failure time. [0003] The current dual-machine hot redundancy backup scheme, such as figure ...
