Joost : A Measurement Study

The potential to broadcast on-demand televisionquality video to a global audience is now possible with the introduction of peer-to-peer Internet television. Joost, originally known as The Venice Project, is a peer-to-peer technology created by the founders of Skype and KaZaA to deliver television-quality, licensed video content. It had taken researchers quite some time to understand the mechanisms and technologies used by Skype, so this paper will begin to unravel the mysteries of Joost through a measurement study. Our contribution will be an understanding of Joost’s application behavior, network behavior, and peer behavior. We will also attempt to explore reasons of peer selection as well as uncovering the benefit of Joost using peer-to-peer as a method of content distribution. Our hope is to provide this information in order to assist in future design or modeling of peer-to-peer video distribution systems.
