Data synchronization method and system and storage medium

Abstract

The invention provides a data synchronization method and system and a storage medium, and the method comprises the steps: transmitting a first message comprising first data to a first external systemthrough a main front-end processor, enabling a standby front-end processor to at least obtain the first data, and restarting a timer; after obtaining the first data, enabling the standby front-end processor to send the first data to the first external system or the second external system; enabling the standby front-end processor to receive the first response message and send a response result to the main front-end processor, and returning the first response message to the standby front-end processor by the external system receiving the first data, wherein the response result is the first response message or information representing that the standby front-end processor receives the first response message; and if the main front-end processor receives a second response message and a responseresult within a first preset duration from the moment when the timer is restarted, determining that the data synchronization is successful, the second response message being returned to the main front-end processor by the first external system after receiving the first message.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data synchronization method, system and storage medium. Background technique [0002] In a large-scale communication network system, a front-end processor is often configured, and generally a front-end processor is a computer. Its main functions are: character or data segmentation and reorganization, data code conversion between terminals, error detection and recovery, protocol support for different terminals, data exchange between terminals, polling terminals, and Data forwarding function. [0003] In order to improve the reliability, availability, maintainability and security of the system, redundant front-end processors (including active front-end processors and backup front-end processors) have become industry standard configurations. Redundant front-end processors can be divided into three redundant modes: cold standby, warm standby and hot standby acco...

Problems solved by technology

[0010] 2. The conventional hot standby redundancy mode is still used, but the external system is required to only accept the data of one of the hot standby hosts and completely discard the data of the other host, which is actually a degraded mode

But this method is ultimately a shift of responsibility, because the source of this data jitter lies in the redundant host. In addition, this method puts forward additional requirements on the external system and increases the burden on the external system.
