Problems solved by technology

[0003] The existing CDN system-based video file synchronization method is to synchronize all video files to each edge IDC in the CND system indiscriminately, the network traffic overhead is large, and the synchronization speed of video files is slow
In addition, for some video files with very low access rate, synchronizing them to the edge IDC will result in low storage utilization of the edge IDC

Abstract

The embodiment of the present invention discloses a video file synchronization method and device. A video file synchronization method includes: obtaining the video metadata information of the target video file; according to the preset correspondence between the video metadata information and the popularity level value , determine the level value pop of the popularity of the target video file, max_pop is the highest level value of popularity, pop∈[0, max_pop); according to the relative relationship between pop and max_pop, the correction coefficient α is calculated; according to the correction coefficient α and given Area identification i, operator type identification j, calculate the number Cij of the Internet data center IDC that needs to receive the target video file; the target video file is synchronized to the Cij IDCs of the jth type operator in the i-th area. Applying the above technical solution, the embodiment of the present invention can synchronize the video files to the IDC in the CDN system in a differentiated manner according to the popularity of the video files. While ensuring user experience, it reduces the network overhead required for synchronization and improves IDC storage utilization.

Description

technical field [0001] The invention relates to the technical field of Internet online video services, in particular to a video file synchronization method and device. Background technique [0002] With the rapid development of Internet online video services, the video-on-demand and live broadcast services provided by Internet online video service providers have become one of the most commonly used Internet services by Internet users. As one of the critical subsystems in the Internet online video service system, the CDN (Content Delivery Network, content distribution network) system is mainly responsible for pre-synchronizing video files to the edge IDC (Internet Data Center, Internet data center) to ensure that users' video access requests can be quickly responded. [0003] The existing CDN system-based video file synchronization method is to synchronize all video files to each edge IDC in the CND system indiscriminately, and the network traffic overhead is large, and the ...
