A traffic control method in p2p file sharing network based on price mechanism

Abstract

The present invention relates to a flow control method in a P2P file sharing network based on a price mechanism. The method is as follows: the prices charged by each initialization of the upload link of the resource provider and the download link of the resource requester; The total traffic adjusts its price at the next moment; the resource provider initializes the download rate for each resource requester; the resource requester gets the price it should pay according to the total traffic it obtains; the resource provider pays the price according to the price paid by the resource requester, The price charged by the download link of the resource requester and the price charged by the upload link of the resource provider adjust the rate allocated to the resource requester at the next moment; the link end and the user end iterate according to the above steps until reaching the optimal point, That is, the optimal traffic allocation strategy for each user. The invention has the advantages of reasonable flow distribution, simple and accurate algorithm, and the like.

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
