SUMMARY:Toward an atlas of the physical internet\, Chaos & Complex Sys
 tems Seminar\, Paul Barford\, UW Department of Computer Sciences
DESCRIPTION:The availability of accurate and timely maps of the Intern
 et would be a compelling starting point for diverse research topics su
 ch as assessing infrastructure vulnerabilities\, understanding routing
  behavior\, and analyzing application performance. However\, despite t
 he many and varied efforts over the years\, there remains no central r
 epository of accurate Internet maps. In this talk\, I will describe th
 e challenges in assembling maps of Internet topology based on standard
  data sources. I will also describes Internet Atlas\, a repository and
  visualization portal of the physical interconnection structure of the
  Internet that has been under construction at the University of Wiscon
 sin for four years. Atlas currently contains PoP/colo and link locatio
 n data for over 1K networks (including all tier 1 providers) around th
 e world. The Atlas repository was the starting point for our recent st
 udy of Internet long haul infrastructure. I will describe key results 
 from that study on deployment characteristics and risks in US long hau
 l infrastructure\, and opportunities to improve performance and robust
 ness.
