When a user installs the Kazaa software on his or her computer, it comes coded with a list of supernodes. Each supernode may serve between 60 and 150 ordinary nodes at one time.

The approximately 30,000 supernodes on Kazaa act a lot like traffic hubs, processing data requests from the slower ordinary nodes. Supernodes are powerful computers with fast network connections, high bandwidth and quick processing capabilities (computer owners don't know that their computers have been designated as supernodes). The system divides Kazaa users into two groups: supernodes and ordinary nodes. FastTrack is a so-called "second generation" P2P protocol. To transfer data between users (peer-to-peer), Kazaa uses the FastTrack protocol.
