A network transmission system, server and client

Abstract

The embodiment of the present invention discloses a network transmission system, a server and a client. The system includes: a resource index server, which is used to return a set of resource links available for download to the client according to the request of the client. The client can connect to the Resource link downloading resources; tracking server, used to obtain the set of user nodes that have resources to be downloaded by the client, and feed back to the client; mutual assistance and cooperation scheduling server, used to accept the registration of user nodes to join the mutual assistance and cooperation organization, in During the resource downloading process of the client, the registered user nodes willing to provide mutual downloading are scheduled to download the resource fragments, and the set of user nodes that have the resources to be downloaded by the client are synchronized with the tracking server. By adopting the invention, clients can help each other to act as agents for downloading tasks, increase the number of copies of scarce resources in the network, and effectively solve the problems of network connectivity and server bandwidth output limitation for a single downloading task.

Description

technical field [0001] The invention relates to the field of network transmission and download, in particular to a network transmission system, a server and a client. Background technique [0002] Peer to server (Peer to Server, P2S) technology is based on user to server, and is the most classic download protocol. "Point" (Peer) is a network node or terminal, which can usually be understood as a user computer. Users (that is, network nodes) directly go to a large download website to download files, and the files are stored on the website server, so the speed can be guaranteed, but the existing problems are scattered resources, difficult to search, and heavy server load. [0003] Point-to-point (Peer to Peer, P2P, or peer-to-peer) technology is a new network transmission technology that has been widely used in file sharing and downloading. It relies on the computing power and bandwidth of participants in the network for transmission. Instead of just relying on a few servers...

Problems solved by technology

Users (that is, network nodes) directly go to a large download website to download files, and the files are stored on the website server, so the speed can be guaranteed, but the existing problems are scattered resources, difficult to search, and heavy server load

[0006] However, in the existing P2SP technology, due to the complexity of the network environment and the limitation of network bandwidth, the connection effect of nodes distributed among different operators is not good

For example, at present, the interconnection speed between the networks of various domestic network operators such as "Telecom, China Unicom, Railcom, Changkuan, Education Network..." is slow

[0007] In addition, some download servers have restrictions on the number of concurrent connections of the client IP. In order to control the download speed of a client, the output bandwidth of the download link is also limited.

The current P2SP download technology has no way to bypass this limitation
