Embodiment Construction

[0030] The present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings, and these embodiments are illustrative and not restrictive.

[0031] Fig. 3 is an embodiment of the present invention. First, build a tree structure as shown in Figure 3 on the operator's server, where the server in Beijing is the root node, and its child nodes are Chaoyang, Haidian, and Xicheng respectively. The child nodes of the Chaoyang node are Asian Games Village, Wangjing, and Jiuxianqiao; the child nodes of the Haidian node are Zhongguancun, Xueyuan Road, and Zizhuyuan. Then, manage the IP address, port number and other information of each node server in the tree structure on a VoD service providing platform.

[0032] The above-mentioned service providing platform also manages end users. Since the terminal user needs to register the location of the user when registering the service, the service provider platform can know the locat...

Abstract

In the invention, a tree structure is established by using a server as root node; each leaf node server of the tree structure is taken as the edge node; each branch node of the tree structure saves the content and releases the content to other subnode. The invention also provides a method for re-directing the user request by means of the content releasing system thereof, and comprises: terminal user sends the content request to its leaf node; if the content requested by the terminal user is saved in the leaf node, then the content is downloaded to the terminal user; otherwise, the terminal user sends the content request to brother node of the leaf node; continuously repeating the steps above until the terminal user downloads the request content or visits the last node server.

Description

(1) Technical field [0001] The invention relates to a content distribution system and a user request redirection method based on the system, in particular to a content distribution system on the Internet and a user request redirection method based on the system. (2) Background technology [0002] Unlike the Public Switched Telephone Network (PSTN), which mainly provides interactive end-to-end symmetric telephone services, the IP network mainly provides asymmetric data services from the server to the client. The information service mode on the IP network is basically that the user applies for the information he wants to obtain from the server storing various information, and the server sends the information content he wants to obtain to the user according to the user's request. The most popular Web service on the IP network is a service based on server / client, and its service model is shown in Figure 1. [0003] As can be seen from Figure 1, when each Web site stores differe...
