Data push, storage and downloading methods and devices based on CDN architecture

Abstract

Disclosed is a data push method based on a CDN architecture. The method comprises the following steps: a push server pushing data identifications of latest data uploaded to a data center to super CDN nodes in the CDN architecture to enable the super CDN nodes to draw the corresponding data from the data center and store the corresponding data in the buffer pool of the super CDN nodes so as to enable the super CDN nodes in the CDN architecture to commonly store a copy of total-amount data of the data uploaded to the data center lately; and the push server pushing storage distribution information of the data in each super CDN node to edge CDN nodes in the CDN architecture to enable the edge CDN nodes to select the super CDN nodes as data drawing sources according to the storage distribution information when drawing the data uploaded in a recent preset time period. The method provided by the invention can improve the data access hit rate of the CDN nodes. Besides, the invention further provides a data push device based on a CDN architecture, and data storage and downloading methods and devices based on a CDN architecture.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a data push method and device based on a CDN architecture, a data storage method and device based on a CDN architecture, and a data download method and device based on a CDN architecture. Background technique [0002] The full name of CDN is Content Delivery Network, that is, content distribution network. Its purpose is to add a new layer of network architecture to the existing Internet, and publish the content of the website to the "edge" of the network closest to the user, so that the user can get it nearby. The required content, improve the response speed of users visiting the website, and solve the problem of network congestion. Technically, it fully solves the problem of slow response speed of users visiting websites due to reasons such as small network bandwidth, large user visits, and uneven distribution of outlets. [0003] The currently commonly used CDN archit...

AI Technical Summary

Problems solved by technology

[0005] In the existing CDN architecture, the data access hit rate of CDN nodes is strongly related to business characteristics. If the access to the same data is relatively concentrated, that is, once there is an access to a certain data, the data access rate in the next period of time will be If the access frequency is high, the data access hit rate of the CDN node is high; otherwise, the data access hit rate of the CDN node is low

[0006] And when the data cached by the CDN node does not hit the access request, the CDN node needs to pull the data from the data center, resulting in expensive data center network traffic
