Problems solved by technology

[0004] However, the existing file content synchronization methods have at least the following disadvantages: as users pay more and more attention to quickly pushing files to service nodes, real-time and timeliness are particularly important for designing news streaming media files
The existing file content synchronization method obtains files from the source server through the set fixed node, but will be affected by the network bandwidth of the source server or the influence of network fluctuations during the synchronization process, and cannot meet the specified time requirement required by the user

Abstract

The embodiment of the invention discloses a method and system for synchronizing a file content, wherein the method comprises: a synchronizing task is sent to a target node synchronization server by a main control server according to the principle of minimum time delay; and the target-node synchronization server successfully downloads a file content from a source station, and then the file contentis downloaded by the synchronization servers of other nodes, thereby completing the content distribution. The system in the embodiment of the invention is corresponding to the method, and composed ofthe main control server as a core, the target-node synchronization server as a download source, and a plurality of node synchronization servers for mutual downloading; and aiming at the defect in theexisting file content synchronization method that the timeliness is poor, the synchronization of the file content and the improvement of the download timeliness of the file content are realized. In addition, in the embodiment of the invention, a mode of monitoring the transmission speeds of paths between the nodes and the source station and searching an optimum source file download path is applied, therefore, the timeliness of file download is further improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, and more specifically, to a file content synchronization method and system. Background technique [0002] Content distribution network CDN is a new type of network construction method, which releases the content of the website to the edge of the network closest to the user in a synchronous form, so that the user can obtain the content they need, solve the network congestion situation, and improve the user's access to the website. responding speed. [0003] The existing content distribution network is based on a fixed node cache server, which provides a mirror image of the content of the source server by downloading the content, and judges the load of the server by the user to ensure that the content requested to be synchronized is provided in an efficient manner for the user's request. Content synchronization service, and reduce the pressure on the master server, improve th...
