Flow control method for P2P file sharing network based on price mechanism

Abstract

The invention relates to a flow control method for a P2P file sharing network based on a price mechanism, and the method comprises the following steps: enabling an uploading link of a resource provider and a downloading link of a resource requester to respectively initialize the received prices; adjusting the price at the next moment according to the total flow of the links; enabling the resource provider to initialize the downloading speed for each resource requester; enabling the resource requester to obtain the price to be paid according to the obtained total flow; enabling the resource provider to adjust the speed at the next moment which is distributed to the resource requester according to the paid price of the resource requester, the received price of the downloading link of the resource requester and the received price of the uploading link of the resource provider; and carrying out the iteration of a link end and a user terminal according to the above steps till the optimal point is reached, i.e., the optimal flow distribution strategy for all users. The method is reasonable in flow distribution, and is simple and accurate in algorithm.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a flow control method of a file sharing network in a peer-to-peer network P2P. Background technique [0002] In recent years, P2P network applications have developed rapidly. On the one hand, the content of the Internet has been enriched. On the other hand, the explosive growth of its traffic and the unrestricted occupation of bandwidth have brought a huge impact on the Internet infrastructure. According to statistics, P2P application services account for more than 80% of all broadband data throughput, and among them, P2P content sharing systems occupy network bandwidth more seriously. Common P2P content sharing systems include file download systems Bittorrent, eDonkey, and Gnutella , search and retrieve Bearshare, content distribution, network storage and peer-to-peer broadcasting Peercasting, etc. [0003] These P2P content sharing systems are rapidly popularized and...

Problems solved by technology

[0004] At present, in terms of P2P traffic control, the traditional control method based on "blocking" is mainly adopted, including strategies such as speed limit, differentiated service, and blocking. Although it can guarantee some key application services in the enterprise network to a certain extent, saving a certain amount Network resources, but these strategies reduce the service quality of P2P applications, make user satisfaction decline, and affect some reasonable P2P applications
