CacheLogic, a world leader in Peer-to-Peer traffic management and network intelligence solutions, released a study of file formats that are used mostly in file sharing over P2P networks. Some of the conclusions found are quite surprising. Firstly we see that Video takes 61.44% of overall P2P traffic by volume (on the four major P2P networks) while audio account for 11.34%. Finally 27.22% goes to other non-audio and non-video file formats.
The study showed that Microsoft video formats represent 46% of aggregate worldwide Peer-to-Peer traffic. 65% of all audio files by volume of traffic are still traded in the MP3 format, but a surprising 12.3% are in the open-source Ogg file format (almost all exclusively traded on the BitTorrent network, particularly in Asia). The study also again showed that the eDonkey2000 network is the "network of choice" for video sharing.
The study also showed that BitTorrent is now increasingly being used for legitimate content distribution. The study is based not on estimates, but on actual packet data and traffic levels analyzed at Tier-One ISPs (Internet Service Providers) worldwide.
