Embodiment Construction

[0046] The preferred embodiments of the invention will be further described in detail below.

[0047] Such as figure 1 As shown, a system for distributing content based on edge wireless hotspots includes a scheduling server, a CDN server, wireless hotspots and users (mobile phones, tablets, personal computers, etc.) located in each sub-area.

[0048] A method for distributing content based on edge wireless hotspots, using the above-mentioned system, comprising the following steps:

[0049] S1, divide the CDN area into multiple sub-areas. First, the CDN area can be divided according to the actual user video viewing record data and the actual wireless hotspot distribution data.

[0050] S2, the wireless hotspot of each sub-area collects the video viewing records of the users in this sub-area and periodically reports to the scheduling server, and the scheduling server predicts the popular video content of each sub-area in the future set time period according to the video viewin...

Abstract

The invention discloses a method and device for distributing content based on edge wireless hotspots, which are characterized in that it includes the following steps: S1, dividing the CDN area into multiple sub-areas; The video viewing record is periodically reported to the scheduling server, and the scheduling server predicts the popular video content of each sub-region in the future set time period according to the video viewing record; S3, when the current bandwidth of the CDN server is less than the set bandwidth, Copy the popular video content to the wireless hotspot in the corresponding sub-area for storage; S4, when the user requests video content, first check whether the wireless hotspot stores the video content, if stored, then directly obtain it from the wireless hotspot, otherwise from the CDN server Request the video content. The present invention can reduce CDN system service overhead while improving user experience.

Description

【Technical field】 [0001] The invention relates to a method and device for distributing content based on edge wireless hotspots. 【Background technique】 [0002] The video traffic in the network increases rapidly and becomes the main part of the network traffic. In order to alleviate the load of CDN content servers, meet the high bandwidth requirements of video distribution, and improve user experience, content distribution service providers deploy more servers to the edge closer to users. However, how close the server should be deployed to the users to meet the user's requirements for service quality improvement and service cost reduction is an urgent problem to be solved. [0003] In order to improve the efficiency of content optimization, the existing methods are mainly divided into: (1) greedily set the optimal location of each server based on the given number of servers; content on edge servers. However, the current method cannot guarantee the optimal user experience a...
