Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Such as figure 1 The data unit synchronization method shown in the mobile environment is used in the edge information service system to realize cloud (i.e. cloud server) side (i.e. edge server) and data collaborative sharing between sides, and it includes the following steps:

[0023] (a) Data unit transmission is carried out in a narrowband network environment, and these data can be electronic intelligence, instruction text, and target information with high real-time requirements.

[0024] (b) The data unit storage management layer periodically checks and obtains incremental log files generated by each data unit; a multi-source data collaborative sharing mechanism can be used for two-way data replication, and at least one data mapping table for both nodes can be established. In order to realize the collaborative sharing of data bet...

Abstract

The invention relates to a data unit synchronization method in a maneuvering environment. The data unit synchronization method comprises the following steps: (a) carrying out data unit transmission ina narrow-band network environment; (b) periodically checking and acquiring incremental log files generated by each data unit by the data unit storage management layer; (c) enabling a data unit storage management layer to acquire a generated incremental log file of the data unit, and encrypts and compresses the file at the source library end; (d) resuming the encrypted and compressed incremental log file to a target library end through a breakpoint, and decompressing and decrypting the incremental log file; and (e) executing the decompressed and decrypted incremental log file statement to finish data synchronization. Therefore, effective transmission synchronization of the data units in a narrow-band network environment can be ensured.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and relates to a method for synchronizing data units, in particular to a method for synchronizing data units in a mobile environment. Background technique [0002] When managing cross-node data, the multi-node mobile information service center needs to realize the synchronous update of multi-node versions in view of the intermittent weak connection characteristics of the mobile environment, so as to solve the version consistency management problem caused by data distribution. Data unit synchronization in a mobile environment is mainly faced with slow data synchronization due to narrow connection and intermittent network disconnection. Contents of the invention [0003] The purpose of the present invention is to provide a method for synchronizing data units in a mobile environment in order to overcome the deficiencies of the prior art. [0004] In order to achieve the above object, th...
