                PPSP Tracker Protocol-Extended Protocol
             draft-huang-ppsp-extended-tracker-protocol-05

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.
