               Peer-to-Peer Streaming Peer Protocol (PPSPP)

Abstract

   The Peer-to-Peer Streaming Peer Protocol (PPSPP) is a protocol for

   disseminating the same content to a group of interested parties in a

   streaming fashion.  PPSPP supports streaming of both prerecorded (on-

   demand) and live audio/video content.  It is based on the peer-to-

   peer paradigm, where clients consuming the content are put on equal

   footing with the servers initially providing the content, to create a

   system where everyone can potentially provide upload bandwidth.  It

   has been designed to provide short time-till-playback for the end

   user and to prevent disruption of the streams by malicious peers.

   PPSPP has also been designed to be flexible and extensible.  It can

   use different mechanisms to optimize peer uploading, prevent

   freeriding, and work with different peer discovery schemes

   (centralized trackers or Distributed Hash Tables).  It supports

   multiple methods for content integrity protection and chunk

   addressing.  Designed as a generic protocol that can run on top of

   various transport protocols, it currently runs on top of UDP using

   Low Extra Delay Background Transport (LEDBAT) for congestion control.
