Abstract

   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.
