    abstract =  {This document specifies an extended Peer-to-Peer Streaming Protocol - Tracker Protocol, which is a new extension protocol complementing the basic core messages and usages specified in the base tracker protocol for the exchange of meta information between trackers and peers, such as initial offer/request of participation in multimedia content streaming, content information, peer lists and reports of activity and status. It extends the base tracker protocol to include new optional messages providing new usages in the communications between peer and tracker. The extension protocol is retro-compatible with the base tracker protocol.},
