Use BitTorrent in a single ISP as an example

pTrackerruns P2P system

iTrackermakes suggestions for peering relationships


Information flow:

1.peer 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 thesuggestions

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.




P4P Architecture (for test)

iTracker is intermediary between ISP’s and P2P’s

Can be operated by ISP’s

Can be operated by third parties
