           PPSP Tracker Protocol-Base Protocol (PPSP-TP/1.0)
                draft-ietf-ppsp-base-tracker-protocol-11

Abstract

   This document specifies the base Peer-to-Peer Streaming Protocol-
   Tracker Protocol (PPSP-TP/1.0), an application-layer control
   (signaling) protocol for the exchange of meta information between
   trackers and peers.  The specification outlines the architecture of
   the protocol and its functionality, and describes message flows,
   message processing instructions, message formats, formal syntax and
   semantics.  The PPSP Tracker Protocol enables cooperating peers to
   form content streaming overlay networks to support near real-time
   Structured Media content delivery (audio, video, associated timed
   text and metadata), such as adaptive multi-rate, layered (scalable)
   and multi-view (3D) videos, in live, time-shifted and on-demand
   modes.
