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

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

Dispelling Myths of P4P
P4P Test Methodology Simulations by Yale on data from AT&T, Telefonica, Verizon Field Test by Telefonica, Verizon, Yale and Pando.
