DESCRIPTION:A substantial amount of work has recently gone into localizing
  \nBitTorrent traffic within an ISP in order to avoid excessive and often 
 \ntimes unnecessary transit costs. Several architectures and systems have 
 \nbeen proposed and the initial results from specific ISPs and few \ntorre
 nts have been encouraging. In this work we set off to deepen and \nscale o
 ur understanding of locality and its potential. Looking at \nspecific ISPs
 \, we consider tens of thousands of concurrent torrents\, and \nthus captu
 re a much more accurate view of ISP-wide implications that \ncannot be app
 reciated by looking at a handful of torrents. Secondly\, we \ngo beyond in
 dividual case studies and present results for the top 100 \nISPs in terms 
 of number of users represented in our dataset of 100K \ntorrents involving
  more than 3.5M concurrent users. We develop scalable \nmethodologies that
  permit us to process the above huge workloads and \naddress yet answered 
 questions like: "what is the minimum and the \nmaximum transit traffic red
 uction across hundreds of ISPs?"\, "what are \nthe win-win boundaries for 
 ISPs and their users?"\, "what is the maximum \namount of transit traffic 
 that can be localized without requiring fine-\ngrained control of inter-AS
  overlay connections and BitTorrent's \nscheduling?"\, "what is the impact
  to transit traffic from increasing the \nspeed of residential connections
 ?".\n\nBio: Nikolaos Laoutaris is a researcher at Telefonica Research\, \n
 Barcelona. Prior to that he was a postdoc fellow at Harvard University \na
 nd a Marie Curie postdoc fellow at Boston University. He holds a Ph.D. \nd
 egree in Computer Science from the University of Athens\, Greece (2004). \
 nHis main research interests are on system\, algorithmic\, and performance
  \nevaluation aspects of computer networks and distributed systems with \n
 emphasis on content distribution\, overlay networks\, P2P\, and multimedia
  \ncommunications.
