Redes P2P: análise de aplicativos P2P

Abstract

The interest in the sharing of data is growing a lot from the appearance of the Internet and one of the main reasons for that has been the easiness of obtaining those data in the net for the increase of the offer, for the improvement of the data transmission speed, for the improvement of techniques of download and for the appearance of nets strictly developed for that purpose. In that last aspect the theme of that work is framed, the nets Peer-to-Peer, or nets point-to-point or, only, P2P and analyze of their applications. The idea is to have connected computers to the net (calls of us, or stop of the net) acting as customers or as servants just depending on the fact of her to be making available (serving) a die in the net (uploading) or obtaining a die of the net (download); being able to that given to be a file or message. Those types of nets were created initially in the intention of sharing music files MP3 but his/her use power goes very besides. Today, already applications exist in the area of distributed computation - software of search of extraterrestrial life of SETI [SETI INSTITUTE 2005], administration of optical nets - I project GigaMan [GRANVILLE 2005] and some projects of applications education colaborativas [RIBEIRO 2003] [ROCHA 2004]. This work doesn't intend to drain the theme and nor to do a meticulous analysis of that or of that net technology, just to wake up still more the interest for a current theme and to analyze their form applications to contribute as source for an eventual study.
