Embodiment 1

[0050] A CDN back-to-source processing method, such as figure 2 As shown, it can include:

[0051] Step 201: Obtain a request for a target resource and back-to-source path information, where the back-to-source path information includes at least a virtual IP address on the back-to-source path of the target source station, and the virtual IP address is configured to perform back-to-source processing of the CDN node;

[0052] Step 202: Forward the request according to the return-to-source path information, so that the request is sent to the target source station.

[0053] In this embodiment, the virtual IP address configured on the CDN node to perform back-to-origin is used to complete the forwarding when back-to-origin. In this way, each CDN node in the CDN system can be used as a forwarding node, which can not only make full use of CDN node resources, but also Effectively improve the speed of returning to the source, thereby effectively improving the acceleration effect of CDN.

example 1

[0084] Such as image 3 As shown, it is an exemplary logical processing diagram of the CDN system after the VIP of the CDN node is bound with different services. Such as image 3 As shown, in each CDN node (CDN node A, CDN node B, CDN node C, CDN node D) configured in the CDN system, VIP2 is bound to the back-to-origin service, VIP1 is bound to the ordinary business service, that is, VIP2 is dedicated To perform back-to-source processing, VIP1 is used to perform ordinary business processing. In this way, the same CDN node can support not only the business logic processing of ordinary business services, but also the forwarding logic processing of back-to-origin services, and it can separate the ordinary business logic processing from the back-to-origin forwarding business logic processing. The logic processing and the forwarding logic processing of the return-to-origin service take different links, so as to make full use of the CDN node resources while increasing the return-to-o...

example 2

[0087] Such as Figure 4 As shown, this is a flowchart of an exemplary execution process of the back-to-source processing method of this embodiment. Such as Figure 4 As shown, the exemplary execution process of the back-to-source processing method of this embodiment may include:

[0088] Step 401: The CDN node receives a request from a terminal, and the request carries domain name information of dynamic data to be obtained, and the dynamic data is the target resource of this example;

[0089] Step 402: Determine whether it is a dynamic accelerated domain name according to the domain name information carried in the request; if it is a dynamic accelerated domain name, proceed to step 404; otherwise, continue to step 403;

[0090] Here, you can determine whether the domain name corresponding to the requested domain name information has the dynamic acceleration service enabled by querying the domain name configuration information issued by the master control node in the CDN system. If t...

Abstract

The invention relates to a back-to-source processing method and device of a CDN, and a system. The method comprises the steps of: obtaining a target resource request and back-to-source path information, wherein the back-to-source path information at least comprises a virtual IP address on a back-to-source path of a target source station; and the virtual IP address is configured to execute back-to-source processing of a CDN node; and, according to the back-to-source path information, forwarding the request, so that the request is transmitted to the target source station. By means of the back-to-source processing method and device of the CDN, and the system disclosed by the invention, the acceleration effect of the CDN on website contents can be at least improved effectively.

Description

Technical field [0001] The present invention relates to the field of Internet technology, in particular to a CDN back-to-source processing method, device and system. Background technique [0002] In related technologies, a content delivery network (CDN, Content Delivery Network) system needs to specifically designate a part of CDN nodes as transit nodes, and can only be forwarded through these transit nodes when returning to the source. Related technologies have at least the following shortcomings: only some nodes can be used as transit nodes, which limits the number of nodes that can be used for forwarding, and cannot make full use of all CDN node resources to perform back-to-source processing, which not only reduces the acceleration effect of CDN on website content , And will cause a waste of resources. Summary of the invention [0003] In view of the above-mentioned deficiencies in related technologies, this application provides a CDN back-to-source processing method, device, ...
