  1. Survey of WebRTC based P2P Streaming draft-huang-ppsp-p2p-webrtc-survey-00 PPSP WG IETF 89 London Rachel Huang, Yunfei Zhang

  2. Goals • Survey of architecture and communication process of current emerging WebRTC based P2P applications. • Promote discussion of the possibility of incorporating P2P streaming into WebRTC.

  3. Traditional Web Based P2P Streaming Applications Web Servers Trackers Tracker protocol HTTP Tracker protocol Tracker protocol HTTP HTTP JavaScript JavaScript JavaScript Plug-in Plug-in Plug-in Peer in Browser Peer in Browser Peer in Browser Peer protocol

  4. SwarmCDN and Peer CDN Web Server Coordinator Private Protocol over HTTP HTTP Private Protocol over HTTP HTTP Data channel JavaScript JavaScript WebRTC Browser WebRTC Browser

  6. P2P Media Streaming with HTML5 and WebRTC- An Experiment from Aalto University

  7. Summary • Current commercial WebRTC based P2P applications are not P2P streaming related. • Obviously, web applications supporting P2P streaming without plug-ins are more and more appealing, since technologies are ready. • The current scope of RTCWEB only points to conversational applications not streaming systems.

  8. Discussions • Should we incorporate P2P streaming in RTCWEB scenarios? • How to support P2P algorithms? (JavaScript can support them or not?) • Do we need WebRTC browsers to support the tracker protocol? • If no, does the tracker protocol need to do some changes? • Do we need WebRTC browsers to support the peer protocol? (data channel already supported) • If no, does the peer protocol need to do some changes? • Any security or performance issues ? e.g., content integrity protection.
