Others, however, use for programs, films, songs, etc. Their number of users is multisplitting mechanisms and permit the download growing every day due to the attractive and interesting from multiple sources, making them suitable for content type that can be found and downloaded over these obtaining larger files. networks. In this article six public architectures are analyzed, Gnutella, FastTrack, Opennap, Edonkey, MP2P These parameters are responsible for an architecture and Soulseek, tracking their evolution during a week in becoming very popular or, on the other hand, terms of connected users, number of files and size of disappearing. The above factors can make a P2P network shared files per hour. The results will be compared and more attractive to users of a specific nation due to the discussed with previous measurements taken a year ago. utilization of a specific language or even social trends [7]. These data can be used to design new network models, to It is also interesting to distinguish between a P2P network calculate their performance or to optimize new network and P2P client, the development of which must not be parameters.
