Problems solved by technology

China has a vast territory, and users from all over the country come to access the search service in Beijing, and the network environment in different areas is also different. When users access the source station in Beijing, there will often be congestion or failure in a certain path in the middle of the path. The network delay of many users is large, which leads to slow access speed
[0004] Usually users directly access the source site, if any link between the user and the source site fails, it will affect the entire access speed

Abstract

The invention provides a method, a system and a device for data access based on a CDN network. The method comprises the following steps: a proxy CDN node receives a first data access message of a client; the proxy CDN node generates a plurality of second data access messages according to the first data access message; the proxy CDN node sends the second data access messages to a source station through a plurality of paths; and the proxy CDN node forwards a first-returned response message in the plurality of paths to the client. According to the proxy CDN node in the embodiment of the invention, the plurality of paths selected by the proxy CDN node enable the proxy CDN node to receive the first-returned response message and send the first-returned response message to the client. Therefore, even if one path is blocked, access of the client is not affected, thus improving the access speed of the client.

Description

technical field [0001] The technical field of the communication network of the present invention particularly relates 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, the source station located in Beijing has to accept search requests from users all over the country. China ...
