  1. P4P Working Group • Doug Pasko, Co-Chair, Verizon • Laird Popkin, Co-Chair, Pando • Haiyong Xie, Principle P4P Researcher, LANS, Yale

  2. P4P Mission Statement • To work jointly and cooperatively with leading Internet service providers (ISPs), peer-to-peer (P2P) software distributors, and technology researchers to ascertain appropriate and voluntary best practices to accelerate distribution of content and optimize utilization of ISP network resources in order to provide the best possible performance to end-user customers

  3. 60+ P4P WG Members

  4. P4P Enables Efficient Delivery P2P P2P with P4P Traditional CDN Internet Transit Regional Routers Edge Network More Viewers = Better performance Lower cost More Viewers = Worse performance Higher cost Network Aware P2P will reduce costs, improve performance 8

  5. pTracker iTracker 2 P4P: Architecture 3 4 1 peer ISP A • Use BitTorrent in a single ISP as an example • pTracker runs P2P system • iTracker makes suggestions for peering relationships • Information flow: • peer queries pTracker • pTracker asks iTracker for guidance (occasionally) • iTracker returns high-level peering suggestions • pTracker selects and returns a set of active peers, according to the suggestions • iTracker can be run by trusted third parties, P2P network, or ISP’s. 10

  6. Network Map (Illustration) 70% PID1 PID2 20% 30% PID6 PID3 10% • Each PID has: • IP “prefix” • Uplink/Downlink Capacity • Links (with weights) • Links weights are directional. 60% PID5 PID4

  7. Weight Matrix (Illustration) Are connected to users in these PID’s Users in PID’s

  8. Dispelling Myths of P4P

  9. P4P Test Methodology • Simulations by Yale on data from AT&T, Telefonica, Verizon • Field Test by Telefonica, Verizon, Yale and Pando.

  10. P4P Architecture (for test) P2P Clients P2P Tracker • iTracker is intermediary between ISP’s and P2P’s • Can be operated by ISP’s • Can be operated by third parties ISP iTracker Telefonica Weight Matrix Yale Pando Network Maps Peer Loc’s Verizon

  11. P4P Test Results • Haiyong

  12. P4P Test Results FTTH 209% faster Non-FTTH 20% faster Slide 18 | Pando Confidential

  13. Implications for ISP’s and P2P’s • Laird Popkin • Doug Pasko

  14. Field Tests • Multi-ISP Field Test in June • Additional P2P Company Field Tests following shortly

  15. Sub-Groups • Caching • Telco • Cable • Hardware • Standards • Research • Live P2P • Wireless • IP Policy/Guidelines
