Method and system for remote resource synchronization of three-tier architecture

Abstract

The invention belongs to the technical field of file synchronization, and in particular relates to a remote resource synchronization method and system with a three-layer structure. The remote resource synchronization method of the three-layer structure of the present invention includes the following steps: the cloud server traverses the local directory, and generates a list file containing all file synchronization information; the offline server obtains the latest list file from the cloud server and compares it with the local list file, and generates a deletion list and download list; the offline server deletes the local file according to the deletion list; the offline server downloads the corresponding file from the cloud server according to the download list; the playback terminal obtains the playback resources in the updated list file of the offline server through the local area network file directory, and obtain the playback resource according to the download address of the playback resource file directory. By adopting the technical solution of the invention, the updated files can be conveniently and efficiently synchronized from the cloud server to the playback terminal.

Description

technical field [0001] The invention belongs to the technical field of file synchronization, and in particular relates to a remote resource synchronization method and system with a three-layer structure. Background technique [0002] In the on-demand application scenarios of digital audio-visual places (such as KTV, bars, etc.), playback terminals need to use a large number of resource files, such as songs, videos, pictures, profiles, etc., in order to ensure the file content of each playback terminal in the same place Usually, these files are managed uniformly by the data center, including adding new files, modifying files, deleting files, etc., and the playback terminal then synchronizes the files from the data center to the local. [0003] The traditional file synchronization method is that the playback terminal deletes all the local data each time, and then synchronizes all the files in the data center to the local. Although this operation is convenient and simple to imp...

Problems solved by technology

[0003] The traditional file synchronization method is that the playback terminal deletes all the local data each time, and then synchronizes all the files in the data center to the local. Although this operation is convenient and simple to implement, you don’t need to care about what operations the data center does to the files, but It is only suitable for the situation where the files in the data center change greatly. If there are not many files updated in the data center each time, the efficiency of this method is very low, which is a serious waste of time and network resources.
