Abstract

The invention provides a content distribution network implementation method based on an SDN, and the method comprises the steps: analyzing an access request received from a client, so as to determine the access information in the access request; generating a new access request according to the access information, wherein the new access request at least comprises access information and an access routing list; transmitting the new access request to the CDN node according to the routing list; judging whether the CDN node is a target CDN node or not according to the new access request: enabling the CDN node to respond to the new access request if the CDN node is the target CDN node, or else, transmitting the new access request to a next CDN node; and giving full consideration to the content of the access request of a user and an optimal path from the user to the nearest node which can provide the content of the access request after the access request from the client is received, thereby guaranteeing that the access request of the user can be met and the optimal path can be provided for the user, improving the quality of the services provided for the user, and guaranteeing the user experience.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and in particular to a method and system for implementing a content distribution network based on SDN (Software Defined Network, SDN). Background technique [0002] CDN (Content Delivery Network, Content Distribution 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] However, in the prior art, the network quality from the user to the user is often not the best, that is, only the nodes that can provide the user with the content ...
