Abstract

The invention discloses a downloading method, a system, a P2P server and a client. The downloading method comprises the following steps that: the client acquires HTTP downloading paths of files to be downloaded and information on other clients capable of providing downloads through seed files; and the client downloads all fragments of the files from HTTP servers and the other clients according tothe acquired HTTP downloading paths and the information on the other clients. By using the method, the system, the P2P server and the client, the bandwidth required to be provided for a server can bereduced.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a downloading method, system, P2P server and client. Background technique [0002] The Hyper Text Transport Protocol (HTTP) is a protocol formulated for sending the content in Web servers located in various parts of the world to an unspecified majority of users. You can also think of HTTP as a protocol designed to distribute files to an unspecified number of users. HTTP is used to read, browse, and download Web pages from a server (Server). [0003] The commonly used HTTP download, simply put, is that the server transmits the content stored on the server to the client (Client) that requests the download. Some HTTP downloads also fragment files to provide downloads in units of fragments. An example is given to illustrate that in existing video websites, a large number of video clips are stored for clients to access and watch or download. The video segment can be divi...
