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 pre-recorded
(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
LEDBAT for congestion control.
