Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The embodiment of the present invention provides a method for real-time data synchronization between the active and standby nodes. After the system is started, the active and standby nodes establish a connection for the first time, and realize the data synchronization from the active node to the standby node through full synchronization, such as figure 1 As shown, full synchronization specifically includes the following steps:

[0025] Step 101: the system is started, and after the master node is powered on and running, start the master node heartbeat task, monitoring task and data synchronization task.

[0026] Step 102: After the standby node is powered on and running, start the task of binding the standby node to the primary node, and establish a connection relationship between the primary and secondary nodes.

[0027] Step 103: De...

Abstract

The invention discloses a real-time data synchronization method and system between main and standby nodes. The method comprises the following steps: starting the system, realizing the data synchronization from a main node to a standby node in a total synchronization mode; after the total synchronization, modifying the configuration parameter of the main node, and realizing the data synchronization from the main node to the standby node in an incremental synchronization mode; during the incremental synchronization, synchronizing the data to the standby node in an internal memory copy mode; and modifying the data by the standby node according to the copied information, and refreshing the configuration parameter according to the modified data. By adopting the real-time data synchronization method and system disclosed by the invention, the instantaneity of data synchronization is obviously improved, and the consistency of the service operation state and the configuration parameter and other information of the device before and after the handover of the main and standby nodes is guaranteed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for real-time data synchronization between active and standby nodes. Background technique [0002] In a modern communication system, especially the central office equipment, because its node position is very important, it is necessary to ensure seamless switching as soon as possible after a failure occurs. For this reason, the equipment is generally equipped with active and standby nodes, that is, the master node ( Master) and standby node (Slave), where the master node is the core of the device, used for performance management, fault management, configuration management and security management of the device, and the standby node is only used as the backup of the master node. When the primary node fails, the system will seamlessly switch between active and standby, and the standby node will take over the work of the primary node to ensure the normal ope...
