Embodiment 1

[0053] see figure 1 as shown, figure 1 It is a flow chart of Embodiment 1 of a redirection method applied to a content distribution network disclosed in an embodiment of the present invention. In this embodiment, the method may include:

[0054] Step 101: the global load balancing server receives a first content access request initiated by a client.

[0055] In a content distribution network, if a user wants to obtain a multimedia content or log in to a website, a content access request needs to be triggered to the global load balancing server GSLB. The content distribution request in this embodiment can be an HTTP or HTPS request.

[0056] Step 102: Determine a content delivery network CDN node meeting preset conditions according to the IP address of the client.

[0057] After GSLB obtains the content access request initiated by the user, it can filter out the content distribution network node closest to the user according to the source IP of the user, and use the CDN node cl...

Embodiment 2

[0075] refer to image 3 as shown, image 3 It is a flowchart of Embodiment 2 of a redirection method applied to a content distribution network disclosed in an embodiment of the present invention. This embodiment may specifically include the following steps:

[0076] Step 301: the user obtains the IP address of the global load balancing server through DNS resolution.

[0077] First, the user can obtain the IP address of GSLB through domain name server (DNS) resolution. For example, if a Beijing Netcom user needs to visit "weibo.com", the local domain name server (LOCAL DNS) will return the IP address of the global load balancing server to user.

[0078] Step 302: the user initiates a first content access request to the global load balancing server through the client.

[0079] The user triggers the client to initiate an HTTP request "GET http: / / weibo.com" to the global load balancing server.

[0080] Step 303: The global load balancing server determines the content delivery...

Embodiment 3

[0099] see Figure 4 as shown, Figure 4 It is a schematic structural diagram of Embodiment 1 of a redirection device applied to a content distribution network disclosed in an embodiment of the present invention. In this embodiment, the device may include:

[0100] A first receiving module 401, configured to receive a second content access request initiated by the client;

[0101] An obtaining module 402, configured to obtain the content requested by the client from the origin server according to the second content access request;

[0102] Specifically, refer to Figure 5 As shown, the acquiring module 402 may specifically include:

[0103] A restoration sub-module 501, configured to restore the second content access to the first content access request;

[0104] A forwarding submodule 502, configured to forward the first content access request to an origin server;

[0105] The obtaining submodule 503 is configured to obtain the content requested by the first content acces...

Abstract

The invention discloses a redirection method and a content distribution node applied to a content distribution network. The method comprises the following steps: a global load balancing server receives a first content access request initiated by a client side, confirms a CDN node conforming to the preset condition according to an IP address of the client side and returns the information of the CDN node to the client side; the CDN node of the content distribution network receives a second content access request initiated by the client side; the CDN node obtains contents requested by the client side from a source station server according to the second content access request; the CDN node extracts a text message in the contents requested by the client side, and an URL of the text message is replaced by an URL of the CDN node; the CDN node returns the URL of the CDN node to the client side. The redirection method can solve the technical problem that in the prior art, a redirection method can aggravate burdens of the server when the page view is higher.

Description

technical field [0001] The present invention relates to the field of content distribution network, and more specifically, relates to a redirection method and content distribution node applied to the content distribution network. Background technique [0002] The full name of CDN is Content Delivery Network, that is, content distribution network. The basic idea is to avoid bottlenecks and links on the Internet that may affect the speed and stability of data transmission as much as possible, so as to make content transmission faster and more stable. Its purpose is to publish the content of the website to the "edge" of the network closest to the user by adding a new layer of network architecture to the existing Internet, so that users can obtain the required content nearby and improve the response speed of users visiting the website . CDN constitutes a layer of intelligent virtual network based on the existing Internet by placing node servers all over the network. The CDN sys...
