Technical Summary

Peer-to-Peer (P2P for short) streaming systems show more and more popularity in current Internet with proprietary protocols. This document identifies problems of the proprietary protocols, proposes the development of Peer to Peer Streaming Protocol (PPSP) including the tracker and peer protocol, and discusses the scope, requirements and use cases of PPSP. 

Working Group Summary

There is strong consensus on the WG process in this document. 

Document Quality

The proposed protocols are being developed and there are already at least three implementations of the PPSP tracker and peer protocol. And there are some operators planning to implement the spec after they are finished.

The draft describes the requirements and problem statements for the standardization of Peer and Tracker streaming protocols that are being specified in separate documents. The Problem Statement draft is not a protocol specification so the question about implementation does not apply. However, there are already both Peer and Trackers streaming protocol implementations.
