Remote resource synchronization method and system for three-layer architecture

Abstract

The invention belongs to the technical field of file synchronization, and specifically relates to a remote resource synchronization method and system for three-layer architecture. The remote resource synchronization method for the three-layer architecture comprises the steps that a cloud server traverses local directories and generates a list file containing all file synchronization information; an offline server obtains a newest list file from the cloud server, compares the newest list file with the local list file and generates a deletion list and a downloading list; the offline server deletes local files according to the deletion list; the offline server downloads corresponding files from the cloud server according to the downloading list; and a playing terminal obtains playing resource file directories in the list file updated by the offline server through a local area network and obtains playing resources according to the downloading addresses of the playing resource file directories. Through adoption of the technical scheme of the method and the system, the updated files can be conveniently and effectively synchronized to the playing 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...

[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.
