Problem Statement and Requirements of Peer-to-Peer Streaming
Protocol (PPSP)
draft-ietf-ppsp-problem-statement-08.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, uses cases and
requirements of PPSP.
