A market study by CacheLogic provides insight on the diversity and levels of file formats traversing the Peer-to-Peer Networks. Traffic analysis focuses on the volume of data flowing through the four dominant P2P networks:
- BitTorrent – a free, open source file-sharing application effective for distributing very large software and media files.
- eDonkey – an application for sharing files across a decentralized Peer-to-Peer network.
- FastTrack – a peer-to-peer protocol (network), used by Kazaa, Grokster, iMesh, and Morpheus file sharing programs (clients).
- Gnutella – the first decentralized network used primarily to exchange music, films and software directly between users.
Video formats represent more than 60% of total P2P traffic, dominated by Microsoft file formats.
Although file sizes vary considerably across all networks, BitTorrent and eDonkey are dominated by large files, FastTrack and Gnutella are dominated by small files.
eDonkey has taken over BitTorrent as the main carrier of file-sharing traffic, possibly due to large torrent directories closing down and eDonkey’s availability in local languages overseas. CNET: P2P users traveling by eDonkey.
BitTorrent is increasingly being used for the distribution of legitimate content.
In terms of audio, the MP3 format dominates with a relatively high level of OGG files found almost exclusively on BitTorrent, particularly in Asia. Here’s OGGLE a search engine for OGG files.
