Method and device for preloading videos in CDN

Abstract

The invention aims at providing a method and device for preloading videos in a CDN. The method specially includes the steps of determining access heat degree information of the videos; determining corresponding preloading information according to the access heat degree information, wherein the preloading information comprises the corresponding to-be-preloaded videos and preloading nodes, corresponding to the to-be-preloaded videos, in the CDN; loading the to-be-preloaded videos on the preloading nodes according to the preloading information. Compared with the prior art, the method and device have the advantages that the corresponding preloading information is determined according to the access heat degree information of the videos so that the to-be-preloaded videos can be loaded on the preloading nodes, distribution of the videos among the different CDN nodes is accordingly optimized according to the access heat degree information of the videos, video storage of the CDN nodes is optimized under the condition that storage space of a machine room server corresponding to the CDN nodes is limited, the efficiency for a user to obtain the videos is improved, and the video access experience of the user is correspondingly improved.

Description

technical field [0001] The invention relates to the field of network video, in particular to a technology for preloading video in a content distribution network. Background technique [0002] The content delivery network (Content Delivery Network, CDN) is a layer of intelligent virtual network based on the existing Internet by placing node servers all over the network. And comprehensive information such as the distance to the user and response time redirects the user's request to the service node closest to the user, which greatly solves the Internet (Internet) network congestion situation and improves the response speed of user access requests. However, the storage space of the computer room servers corresponding to the CDN nodes is limited, and users in different regions have different interests in videos. The existing technology cannot back up all videos at each CDN node to meet the different video access needs of users. When the users in the area served by the backup vi...

Problems solved by technology

However, the storage space of the computer room servers corresponding to the CDN nodes is limited, and users in different regions have different interests in videos. The existing technology cannot back up all videos at each CDN node to meet the different video access needs of users. When users in the area served by the backup video CDN node are not very interested in the video, the CDN node will not be able to fully function, resulting in waste of node resources, and when the node performance of the backup video CDN node cannot meet the needs of users in the corresponding area When there is a demand for video playback, the CDN node cannot provide users with good services, such as incoherent video playback, out-of-sync video sound and real-time online data, etc., and even the video cannot be loaded, which affects the user's video access to experience
