Pre-distribution processing method and device of content distribution network

Abstract

The invention provides a pre-distribution processing method and device of a content distribution network. The method comprises the following steps: determining a list of an edge server needing to be pre-distributed according to a pre-set condition, wherein the pre-set condition comprises at least one of an edge server service condition reported by the edge server and a pre-distribution region appointed by a content supplier; and pre-distributing the edge server in the list. With the adoption of the technical scheme provided by the invention, the problems that files only can be distributed in the whole network so that the consumed time is relatively long, and each CDN edge node can generate a relatively large back-to-source bandwidth in a whole network pre-distribution process so that the bandwidth load of a customer source station is relatively high can be solved; and which edge servers need to be pre-distributed can be judged according to the pre-set condition so that the whole network pre-distribution is avoided, and the time and the bandwidth expenditure are saved, and the pre-distribution target effect can be realized to the greatest extent.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a pre-distribution processing method and device for a content distribution network. Background technique [0002] Pre-distribution is one of the basic functions of Content Delivery Network (CDN) service, which is to pre-load hot large files (such as videos, software, etc.) onto CDN edge nodes, and then open them to netizens access to improve the access efficiency of Internet users when they initially visit. [0003] After the CDN service provider receives the pre-distribution task of a certain channel of the customer, it will send the distribution task to all CDN edge node servers of the channel; after receiving the instruction, all CDN edge servers will pull the specified file from the source station and store it. It is cached locally on the server; after all the edge servers have been pulled, the customer will be notified of the success of the pre-distribution task, ...

AI Technical Summary

Problems solved by technology

[0004] In related technologies, files will be delivered to edge node servers in the form of pre-distribution across the entire network, but this takes a long time, and each CDN edge node will generate a large back-to-source bandwidth, resulting in a heavy bandwidth load on the customer's origin site. High, although related technologies also provide a technical solution for pre-distributing nodes in some areas according to artificial selection, but such a technical solution is not very accurate first, and secondly, the edge server for pre-distribution is not necessarily the most current Servers that need to be pre-distributed

[0005] In related technologies, there is currently no effective technical solution to realize targeted pre-distribution by region according to the current service status of the edge server
