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

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

5 10 ISP A P4P: Architecture 1 4 3 2 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.

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) iTracker is intermediary between ISPs and P2Ps Can be operated by ISPs Can be operated by third parties Yale Telefonica Verizon Network Maps Pando Weight Matrix Peer Locs ISP iTracker P2P Tracker P2P Clients
