FastTrack


FastTrack

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 because of licensing disputes.

In 2003, FastTrack was the most popular file sharing network, being mainly used for the exchange of music mp3 files.

The network had approximately 2.4 million concurrent users in 2003. It is estimated that the total number of users was greater than that of Napster at its peak.

While the FastTrack protocol is used in file-sharing software it is also used in other entities that share the same name, such as FastTrack and the Netscape FastTrack Server.

History

The FastTrack protocol and Kazaa are the brainchild of Niklas Zennström from Sweden, Janus Friis from Denmark and Estonian programmers headed by Jaan Tallinn, the same team that later created Skype. It was introduced in March 2001 by their Dutch company Consumer Empowerment. It appeared during the end of the first generation of P2P networks – Napster shut down in July of that year.

Currently, three FastTrack-based networks exist, using mutually incompatible versions of the protocol. The most popular clients on each are Kazaa (and its variations), Grokster, and iMesh. References to "the" FastTrack network" usually apply only to Kazaa's.

Technology

FastTrack is a so-called second generation P2P protocol. It uses supernodes to improve scalability.

To allow downloading from multiple sources, FastTrack employs the UUHash hashing algorithm. While UUHash allows very large files to be checksummed in a short time, even on slow computers, it also allows for massive corruption of a file to go unnoticed. Many people, as well as the RIAA, have exploited this vulnerability to spread corrupt and fake files on the network.

Clients

The FastTrack protocol uses encryption and was not documented by its creators, and the first clients were all closed source software. However, initialization data for the encryption algorithms is sent in the clear and no public key encryption is used, so reverse engineering was made comparatively easy. In 2003, open source programmers succeeded in reverse-engineering the portion of the protocol dealing with client-supernode communication, but the supernode-supernode communication protocol remains largely unknown.

The following programs are or have been FastTrack clients:
* Kazaa and variants
* KCeasy (requires the gIFT-fasttrack plugin)
* Grokster
* iMesh
* Morpheus, until 2002
* Apollon - A KDE-Based P2P client
* giFT-FastTrack [http://developer.berlios.de/projects/gift-fasttrack/] – a giFT plugin
* MLDonkey, a free multi-platform multi-network file sharing client
