SUMMARY:Toward an Atlas of the Physical Internet - Paul Barford  (Universi
 ty of Wisconsin-Madison)

DESCRIPTION:The availability of accurate and timely maps of the Internet w
 ould be a compelling starting point for diverse research topics such as as
 sessing infrastructure vulnerabilities\, understanding routing behavior\, 
 and analyzing application performance.  However\, despite the many and var
 ied efforts over the years\,  there remains no central repository of accur
 ate Internet maps.  In this talk\, I will describe the challenges in assem
 bling maps of Internet topology based on standard data sources.  I will al
 so describes Internet Atlas\, a new repository and visualization portal of
  the physical interconnection structure of the Internet that is under cons
 truction at the University of Wisconsin.  The repository is populated usin
 g web-based information extraction to identify primary source data such as
  maps and other repositories of service provider network information.  The
  repository currently contains over 8K PoP locations and nearly 13K links 
 for over 275 networks (including all tier 1 providers) around the world.  
 The openly available web portal is based on the widely-used ArcGIS geograp
 hic information system\, which enables visualization and diverse spatial a
 nalyses of the data.  To demonstrate the utility of the repository\, I wil
 l describe two case studies:  a first-of-it's kind analysis of physical li
 nk distances and an analysis of natural disaster threats to Internet infra
 structure.\n\nBio: Paul Barford is a professor of Computer Sciences at the
  University of Wisconsin - Madison.  He was a visiting professor at the Un
 iversity of Cambridge and an EPSRC Visiting Fellow in 2011.  His research 
 interests are in Internet measurement\, large data analysis\, Internet sec
 urity\, and sustainable networking.   \n
