Peer-to-Peer Streaming Tracker Protocol (PPSTP)
Abstract
This document specifies the base Peer-to-Peer Streaming Tracker
Protocol (PPSTP) version 1, 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; it also describes message flows, message
processing instructions, message formats, formal syntax, and
semantics. The PPSTP enables cooperating peers to form content-
streaming overlay networks to support near real-time delivery of
structured media content (audio, video, and 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.
