                  Survey of P2P Streaming Applications
                       draft-ietf-ppsp-survey-03

Abstract

   This document presents a survey of popular Peer-to-Peer streaming
   applications on the Internet.  We focus on the Architecture and Peer
   Protocol/Tracker Signaling Protocol description in the presentation,
   and study a selection of well-known P2P streaming systems, including
   Joost, PPlive, andother popular existing systems.  Through the
   survey, we summarize a common P2P streaming process model and the
   correspondent signaling process for P2P Streaming Protocol
   standardization.

Internet-Draft    Survey of P2P Streaming Applications      October 2012

1.  Introduction

   Toward standardizing the signaling protocols used in today's Peer-to-
   Peer (P2P) streaming applications, we surveyed several popular P2P
   streaming systems regarding their architectures and signaling
   protocols between peers, as well as, between peers and trackers.  The
   studied P2P streaming systems, running worldwide or domestically.
   This document does not intend to cover all design options of P2P
   streaming applications.  Instead, we choose a representative set of
   applications and focus on the respective signaling characteristics of
