GoalBit: P2P Streaming Goes Open Source

Janko Roettgers writes about a release of an open source bittorrent streaming apps:

GoalBit uses a hybrid approach that combines the best of the BitTorrent world, with features from the likes of P2P networks such as Gnutella and KaZaA’s FastTrack network. Its network features a tracker similar to the one used by BitTorrent clients, but it also makes use of so-called super-peers. These are computers with fat pipes that help to distribute the initial signal until it trickles down to users with ordinary DSL connections and limited upload speeds. Super-peers can be run either by the broadcasters themselves, or self-selected based on the connectivity of the individual end user. The idea of this multilayer approach is to prevent too many direct connections to the broadcaster while at the same time making the system scalable.
