Problems solved by technology

[0016] The purpose of the embodiments of the present invention is to provide a method and system for point-to-point P2P content sharing, aiming to solve the problems in the prior art that private network users cannot realize P2P sharing and the access rate of P2P sharing is limited by the smaller of the uplink or downlink rate. The problem with rate limiting

Embodiment Construction

[0029] The technical solution provided by the embodiment of the present invention is that in the existing BT network architecture, users with certain conditions are used as super nodes, and these super nodes act as STUN Server (STUN server) or TURN Server (TURN server). Private network users traverse NAT to play the role of coordinating transit. In addition, supernodes are obliged to provide upload services when they have no download needs. The upload service provided by supernodes makes up for the insufficient upload rate, so that the upload rate can reach the download speed. rate requirements.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the ...

Abstract

The method includes following steps: after receiving request for applying banding from general user node, super node checks up whether self stores banding applied by general user; if yes, uploading the stored banding for general user node to share; otherwise, applying to other super nodes or general user nodes for banding applied by general user; then uploading the obtained banding for general user node to share. The invention can help private network user behind NAT to pass through NAT to realize P2P transmission. The invention also solves issue that in asymmetric network between up going rate and down going rate, integral sharing rate is limited by minimum rate. Thus, the invention makes real time P2P commercial application with higher requirement on bandwidth become possible.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to the content sharing technology in the Internet. Background technique [0002] The traditional Internet adopts the client / server method and uses centralized servers on the website, but the development trend of the Internet will change from centralized to distributed, and centralized servers will become distributed, such as P2P (Peer to Peer point-to-point) technology. [0003] P2P technology combines many users into a network, shares the bandwidth, and processes the information together. Different from the traditional client / server mode, in the P2P working mode, each client terminal is both a client and a server. [0004] P2P sharing download is a relatively common download mode at present. Tens of millions of Internet users around the world use BT (Bit Torrent) software to download entire movies, MP3 and large-scale software every day. More than 70% of traffic....
