Method and device for preloading video in content distribution network

Abstract

The invention aims at providing a method and a device for preloading a video in a content distribution network. The method comprises the steps of determining the video to be preloaded and a preloading node corresponding to the video to be preloaded in the content distribution network; determining a preloading path corresponding to the video to be preloaded in the content distribution network according to the video to be preloaded and the preloading node; loading the video to be preloaded to the preloading node from the corresponding source node based on the preloading path. Compared with the prior art, the video to be preloaded is loaded to the preloading node from the corresponding source node based on the preloading path which is determined primarily, therefore, the purpose of loading the video to be preloaded to the corresponding preloading node on the basis of the preloading path of the video to be preloaded is achieved, few network resources are consumed by video loading, time is short, video loading efficiency is increased, and users' video access experience is 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] With the development of network technology and video applications, more and more people not only like to communicate and interact through the network, but also like to watch videos, such as watching live video and video on demand through the network. In order to improve the user's access experience to the video, the existing content distribution network (Content Delivery Network, CDN) technology is usually used to back up the video on the CDN node, so as to real-time according to the network traffic and the connection and load status of each node, as well as the user's Comprehensive information such as distance and response time will redirect the user's request to the service node closest to the user, which greatly solves the Internet (Internet) network congestion situation and improves...

AI Technical Summary

Problems solved by technology

However, users in different regions have different interests in the same video, and users in the same region have different needs for different videos. In order to meet the diverse video needs of users, it is necessary to back up different videos on the CDN node to satisfy users in the region served by the CDN node. However, when the video is loaded to the corresponding CDN node, if the loading path is not selected properly, more network resources will be consumed, and the loading time will be longer, which will affect the user's video access experience
