FastTrack is a
peer-to-peer (P2P)
protocol, used by the
Kazaa (and variants,
Grokster and
iMesh)
file sharing programs. The file sharing application
Morpheus originally used this network, but was later banished from it.In
2003, FastTrack was the most popular file sharing network, being mainly used for the exchange of music
mp3 files. Popular features of FastTrack are the ability to resume interrupted downloads and to simultaneously download segments of one file from multiple peers.The network had approximately 2.4 million concurrent users in 2003. It is estimated that the total number of users is greater than that of
Napster at its peak. (Note: This information isn't up to date.)
