Problems solved by technology

Moreover, in the device that starts first, the data to be synchronized cannot be guaranteed to exist continuously in the memory. If the memory is directly transferred, a lot of unnecessary data will be transferred, resulting in great redundancy

Abstract

The invention provides a method for synchronizing data between different equipment. The method comprises the following steps: (a) first equipment records the initial position and length of each data item needing to be synchronized in the memory of the first equipment; (b) the first equipment constructs each data item needing to be synchronized into a synchronous message which can be transmitted to second equipment according to the recorded initial position and length information of each data item and sends the synchronous message to the second equipment, and if the length of each data item is more than the maximum allowable message length between the first equipment and the second equipment, the data item is split into a plurality of synchronous messages with the length less than the maximum allowable message length; and (c) the second equipment memorizes the received data into the memory of the second equipment and the memory position is the same as that of the received data in the memory of the first equipment.

Description

technical field [0001] The invention relates to the technical field of communication and computer, in particular to a method and device for synchronizing data between different devices. Background technique [0002] One of the important technologies for seamless switching between the active device and the standby device is the data synchronization technology between the two devices. After two boards with the same function are started up successively, the board started later needs to seek the data to be synchronized from the board started up earlier. [0003] The synchronization process between the master device and the backup device is usually as follows: the backup device sends a synchronization request to the master device; the master device sends a synchronization data message to the backup device; Complete message. Some synchronization mechanisms further send a response message to the active device after the backup device receives the synchronization data, so as to ens...
