Abstract

The present invention relates to a multi-caching server-based scheduling method and device, wherein the method includes: receiving a video playback request from a viewing terminal to obtain a video file path; performing a hash operation on the video file path to obtain a first hash value, and performing the hash operation on the video file path Scan the ring counterclockwise, and determine the hash value in the hash ring that is closest to the first hash value and associated with the edge cache node that is not overloaded as the second hash value, and the non-overloaded node associated with the second hash value The edge cache node is used as the main cache node for performing the video file caching task, and the address of the main cache node is spliced ​​to generate the redirection path of the video file, so as to redirect the viewing terminal to the main cache node. The invention fully considers the affinity between the content and the edge cache node and the load of the edge cache node, can obtain the most suitable main cache node and redirect the playback request of the viewing terminal to the main cache node, and improves the cache hit rate.

Description

technical field [0001] The invention relates to the technical field of streaming media live broadcast on demand, in particular to a scheduling method and device based on multiple cache servers. Background technique [0002] With the development of Internet multimedia technology and the continuous increase of network bandwidth, online video has attracted a large number of users with its convenient access experience, diversified video sources, and real-time update speed, making online video an indispensable part of users' online life. essential component that is missing. [0003] At present, major Internet video sites mainly use sliced ​​transmission protocols, including Apple's HLS (HTTP Live Streaming, dynamic bit rate adaptive technology), Adobe's HDS (Hitachi DataSystems), and the MPEG- DASH; these slicing transmission protocols all have something in common: the underlying transmission adopts the HTTP / HTTPS protocol; the live stream or on-demand video file data is divided...
