Abstract:
The Peer-to-Peer Streaming Peer Protocol (PPSPP) is a peer-to-peer
based transport protocol for content dissemination. It can be used
for streaming on-demand and live video content, as well as
conventional downloading. In PPSPP, the clients consuming the
content participate in the dissemination by forwarding the content to
other clients via a mesh-like structure. It is a generic protocol
which can run directly on top of UDP, TCP, or as a RTP profile.
Features of PPSPP are short time-till-playback and extensibility.
Hence, it can use different mechanisms to prevent freeriding, and
work with different peer discovery schemes (centralized trackers or
Distributed Hash Tables). Depending on the underlying transport
protocol, PPSPP can also use different congestion control algorithms,
such as LEDBAT, and offer transparent NAT traversal. Finally, PPSPP
maintains only a small amount of state per peer and detects malicious
modification of content. This documents describes PPSPP and how it
satisfies the requirements for the IETF Peer-to-Peer Streaming
Protocol (PPSP) Working Group's peer protocol.
