Paul Barford, University of Wisconsin

Paul Barford is a professor of Computer Sciences at the University of Wisconsin - Madison, and the founder and director of the Wisconsin Advanced Internet Lab. He was a visiting professor at the University of Cambridge and an EPSRC Visiting Fellow in 2011. He was the founder of Nemean Networks, LLC, which was acquired by Qualys, Inc. in 2010. He was the co-founder of MdotLabs, Inc., which was acquired by comScore Inc. in 2014, where he now serves as Chief Scientist. His research interests are in networking, data analytics, and security. Prof. Barford is a frequent speaker, has many highly-cited research papers, and has served on numerous panels, organizing committees, and program committees (ACM SIGCOMM '13 TPC co-chair, ACM SIGMETRICS '10 TPC co-chair, and ACM IMC '06 TPC chair). He has served as an associate editor for IEEE/ACM Transactions on Networking, on the board of directors of the National Lambda Rail, and on technical advisory boards of companies.
Abstract: The availability of accurate and timely maps of the Internet would be a compelling starting point for diverse topics such as assessing infrastructure vulnerabilities, understanding routing behavior, and analyzing application performance. However, despite the many and varied efforts over the years, there remains no central repository of accurate Internet maps. In this talk, I will describe the challenges in assembling maps of Internet topology based on standard data sources. I will also describe Internet Atlas, a new repository and visualization portal of the physical interconnection structure of the Internet that is under construction at the University of Wisconsin. The repository is populated using 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 9K PoP locations and nearly 14K links for over 390 networks (including all tier 1 providers) around the world. The openly available web portal is based on the widely-used ArcGIS geographic information system, which enables visualization and diverse spatial analyses of the data. To demonstrate the utility of the repository, I will describe an analysis of natural disaster threats to Internet infrastructure and how these risks can be reduced through the use of an optimization framework that identifies locations for provisioning additional infrastructure.
