Embodiment 1

[0053] The embodiment of the present invention provides a CDN back-to-source method, which can be applied to a CDN system, such as figure 1 As shown, the methods of CDN back-to-source include:

[0054] S101. The first server acquires a file request instruction, where the file request instruction includes an identifier of a requested file.

[0055] CDN is a layer of intelligent virtual network based on the existing Internet formed by placing node servers all over the network. In the prior art, the method for the server to perform back-to-source is usually to go to another server to perform back-to-source according to the fixed back-to-source address configured inside the server. However, in the prior art, since the server can only perform back-to-origin according to the fixed back-to-origin address configured inside the server, it is impossible to flexibly assign the back-to-origin address to the server. Moreover, when many servers go to a fixed back-to-origin address to go b...

Embodiment 2

[0072] The embodiment of the present invention provides a CDN back-to-source method, which can be applied to a CDN system, such as figure 2 As shown, the methods of CDN back-to-source include:

[0073] S201. The first server acquires a file request instruction, where the file request instruction includes an identifier of a requested file.

[0074] CDN is a layer of intelligent virtual network based on the existing Internet formed by placing node servers all over the network. Since the server in the prior art can only perform back-to-source based on the fixed back-to-source address configured inside the server, it is impossible to flexibly assign the back-to-source address to the server. Moreover, when many servers go to a fixed back-to-origin address to go back to the source at the same time, the access pressure of the servers that provide the back-to-source will be unbalanced, resulting in system overload and unreasonable utilization of system resources, which will affect t...

Embodiment 3

[0106] An embodiment of the present invention provides a first server, which can be applied to a CDN system, such as image 3 As shown, the first server includes:

[0107] The first obtaining module 10 is configured to obtain a file request instruction, where the file request instruction includes an identifier of the requested file.

[0108] A judging module 11, configured to judge whether the file corresponding to the identifier is stored in the first server.

[0109] The second obtaining module 12 is configured to obtain a dynamic back-to-source address if the file is not stored in the first server.

[0110] The download module 13 is configured to download the file from the second server according to the dynamic back-to-source address.

[0111] Further, as Figure 4 As shown, the first server further includes:

[0112] The first response module 14 is configured to respond to the file request instruction if the file is stored in the first server.

[0113] Further, as F...

Abstract

The embodiment of the invention provides a CDN back-to-source method, a first server and a system thereof, and relates to the field of network multimedia technology. According to the invention, a dynamic back-to-source address can be flexibly allocated for a server such that the server can flexibly carry out back-to-source operation according to the dynamic back-to-source address. Thus, visit pressure of a CDN system is balanced; system overload is avoided; system resources are utilized reasonably; and performance of the CDN system is improved. The method comprises the following steps: the first server acquires a file request instruction which contains an identifier of a requested file; the first server judges whether a file corresponding to the identifier is stored in the first server; if the file is not stored in the first server, the first server acquires the dynamic back-to-source address; and the first server downloads the file from a second server according to the back-to-source address.

Description

technical field [0001] The present invention relates to the field of network multimedia technology, in particular to a CDN back-to-source method, a first server and a system. Background technique [0002] CDN (Content Delivery Network) is a layer of intelligent virtual network based on the existing Internet formed by placing node servers throughout the network. CDN can redirect the user's request to the service node closest to the user based on comprehensive information such as network traffic, connection of each node, load status, distance to the user, and response time in real time. The nodes send the content required by the user to the user, relieve the network congestion, and improve the response speed of the website. [0003] When the server is responding to the instruction input by the user, if the file indicated by the instruction input by the user does not exist in the server, it is usually necessary to go to another server for back-to-source. In the prior art, the...
