        Problem Statement of Peer-to-Peer Streaming Protocol (PPSP)
                 draft-ietf-ppsp-problem-statement-07.txt

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 and uses cases of PPSP.
