Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0030] Such as Figure 4 Shown: in order to be able to realize the acceleration to dynamic content in CDN system, improve the data transmission efficiency between CDN node and source site, the present invention comprises source site and CDN node pool; Build between described source site and CDN node pool A virtual acceleration network, the CDN nodes in the CDN node pool are connected to the source site through a virtual acceleration network; several acceleration nodes are included in the virtual acceleration network, and a tunnel connection is established between the acceleration nodes through a VPN;

[0031] The CDN node in the CDN node pool can access the acceleration node closest to the CDN node as the access node, and the virtual acceleration network selects the acceleration node closest to the source site as the outbound node according to the location wher...

Abstract

The invention relates to a CDN (content delivery network) dynamic acceleration system and method. The CDN dynamic acceleration system comprises a source site and a CDN node pool, wherein a virtual acceleration network is constructed between the source site and the CDN node pool; an optimum CDN node in the CDN node pool is connected with the source site via the virtual acceleration network; the virtual acceleration network comprises a plurality of acceleration nodes; the acceleration nodes establish tunnel junction by a VPN (virtual private network); the CDN node in the CDN node pool can be accessed into an acceleration node which is nearest to the CDN node as an access node; the virtual acceleration network selects the acceleration node nearest to the source site according to the position on which the CDN node needs to be connected with the source site as an outbound node to realize connection between the CDN node and the source site; after the outbound node receives the reply of the source site, the reply of the source site is sent to the CDN node via the access node. According to the CDN dynamic acceleration system disclosed by the invention, the dynamic content can be accelerated, the data transmission efficiency between the CDN node and the source site can be improved and guaranteed, and the CDN dynamic acceleration system has the advantages of wide applicable range, safety and reliability.

Description

technical field [0001] The present invention relates to a system and method, in particular to a CDN dynamic acceleration system and method, belonging to the technical field of CDN. Background technique [0002] The full name of CDN is Content Delivery Network, that is, content distribution network. The basic idea is to place node servers all over the network to form a layer of intelligent virtual network based on the existing Internet through node servers, so as to avoid possible speed bottlenecks and unstable network links on the Internet. Make content transmission faster and more stable. [0003] The CDN system can redirect the user's request to the service node closest to the user through intelligent DNS based on comprehensive information such as network traffic, connection of each node, load status, distance to the user, and response time in real time, so that the user can get closer Obtain the required content, solve the crowded situation of the Internet network, and ...
