Video file synchronization method and video file synchronization device

Abstract

An embodiment of the invention discloses a video file synchronization method and a video file synchronization device. The video file synchronization method includes: acquiring video metadata information of a target video file; determining a popularity level value pop of the target video file according to corresponding relation between preset video metadata information and popularity level values, wherein max_pop refers to the maximum popularity level value, and pop<[0, max_pop); calculating to obtain a correction factor alpha according to the relation between the pop and the max_pop; calculating the number Cij of IDCs (internet data centers) needing to receive the target video file according to the correction factor alpha and a given region identification i and an operator type identification j; synchronizing the target video file onto Cij IDCs of the jth type of operator in the ith region. By application of the technical scheme, the video file can be differentially synchronized onto the IDCs of in a CDN (content delivery network) system according to the popularity of the video file. Therefore, network expenditure required by synchronization is reduced while user experience is guaranteed, and storage utilization rate of the IDCs is increased.

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) in the CDN system that is closer to the user. , Internet data center) to ensure that users' video access requests can be quickly responded to. [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, ...

AI Technical Summary

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
