Abstract

The invention proposes a data access method, system and device based on a CDN. The method includes the following steps that an agent CDN node receives a data access message of a client side; the agent CDN node sends the data access message to a source station; the agent CDN node receives a response message fed back by the source station, wherein the response message is relevant to data requested by the client side; the agent CDN node generates the data requested by the client side according to the response message and local data, and the data are transmitted to the client side. According to the data access method, system and device based on the CDN, the source station does not need to feed back complete data and only needs to feed back the response message relevant to the data, and therefore the amount of the data needing to be transmitted is reduced, and the access to dynamic pages can be accelerated for a user in a traditional CDN mode.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a data access method, system and device based on a CDN (Content Delivery Network, content distribution network) network. Background technique [0002] The development of the Internet has brought great convenience to life. People can search all kinds of information from all over the world in front of a computer without leaving home, and log in to the web pages of major portal websites. Everything that happened can be seen at a glance. For the information that users want to get, they only need to enter the corresponding keywords in the search bar, and then click OK, and tens of thousands of relevant information will be displayed instantly, saving the inconvenience of books, papers and traveling. It saves time and enriches our life. [0003] However, at present, many important web pages are dynamic pages. The so-called dynamic pages or dynamic objects refer ...
