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 a
   Peer to Peer Streaming Protocol (PPSP) including tracker and peer
   signaling components, and discusses the scope, uses cases and  
   requirements of PPSP.
