         PPSP Tracker Protocol--Extended Protocol (PPSP-TP/1.1)
             draft-huang-ppsp-extended-tracker-protocol-01

Abstract

   This document specifies the extended Peer-to-Peer Streaming Protocol
   - Tracker Protocol (PPSP-TP/1.1), a new extension protocol
   complementing the basic core messages and usages specified in
   PPSP=TP/1.0  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 PPSP-TP/1.0 to include new
   optional messages providing granular controls and usages in the
   communications between peer and tracker. The extension protocol is
   retro-compatible with PPSP-TP/1.0.
