specific Embodiment 1

[0063] Specific embodiment 1: see Table 1 below, which is a backup relationship table provided for specific embodiments of the present invention.

[0064] In the backup relationship table, ucModule, usGroup, and ucSGroup represent the logical address of the main board in the N+M backup group, and ausBakGroup1List / aucBakSGroup1List, ausBakGroup2List / aucBakSGroup2List, ausBakGroup3List / aucBakSGroup3List represent the backup boards in the N+M backup group, respectively. That is, the logical address list of the backup board, where ausBakGroup1List / aucBakSGroup1List is the preferred backup group list. If the main board in the current backup group fails, the backup board in the backup group is preferably replaced as the main board. If all the boards in the current preferred backup group are faulty, select the normal backup boards in backup list 2 and backup list 3 in order to replace them as masters.

specific Embodiment 2

[0067] Specific embodiment 2: In a communication device, the data on each peripheral board needs to be consistent with the data on the central node, and data consistency between the active and standby peripheral boards must also be maintained. In order to ensure the validity and consistency of the data on each board, it is necessary to ensure the data synchronization of the database subsystem. The structure of the database subsystem is designed as a distributed processing method, and the database relationship sets are distributed on the processors of each node. The synchronization of the database subsystem specifically includes: static data synchronization and dynamic data synchronization.

[0068] Static data is the configuration data sent by the central node. When the peripheral boards are initialized and powered on, the data of the central node needs to be synchronized to each peripheral board. The static data synchronization process during the power-on process of the perip...

specific Embodiment 3

[0087] Specific embodiment 3: the logical addresses of the main board and the backup board are configured in the backup relationship table, and the logical addresses are virtual. Only by mapping the logical address to the physical address of the peripheral single board can the relationship of the single board in the backup relationship table be Corresponds to the real single board; when the system is initialized, the mapping relationship is configured by the central node. The backup relationship table and mapping relationship will be sent to all peripheral nodes.

[0088] When the active / standby switching occurs during the operation of the N+M peripheral board, it is necessary to exchange the mapping relationship between the logical address and the physical address of the active / standby board. The logical address configured as active is used, and the logical address configured as standby is used for the downgraded physical board, so as to ensure the normal communication betwee...

Abstract

The embodiment of the invention provides a data synchronization method and device which are used for configuring the main-standby relationship between peripheral nodes and synchronizing the node resource data. The method comprises the following steps: the peripheral nodes receive the main-standby state information sent by a central node, wherein the main-standby state is determined by the central node according to a main-standby relationship table containing the corresponding relationship between the virtual address of the main peripheral node and the virtual address of the standby peripheral node and the mapping relationship between each current virtual address and the physical address of each peripheral node; and if a peripheral node is determined as a main peripheral node according to the main-standby state information sent by the central node, the network configuration data sent by the central node is received.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a data synchronization method and device. Background technique [0002] The telecommunications equipment system consists of multiple nodes and distributed applications on each node to work together. When a node's hardware or software subsystem fails in the system, it will inevitably affect the normal operation of the entire system. Therefore, the equipment system is required to provide a hot backup mechanism on key resources. Most of the key resources in the traditional form adopt the 1+1 backup mode. [0003] Most of the existing equipment adopts the 1+1 active-standby working mode. The active node synchronizes the configuration data and resource status data to the standby node in real time. When the active node fails or receives a forced active-standby switchover command from the network Real-time upgrade to master, and ensure that the services that have been accessed by t...
