Abstract: The ever-increasing demand for content has reshaped the Internet bringing serving infrastructure to the proximity of the users. However, recent studies showed that the rich and complex interdependencies in the web ecosystem are often served from remote locations only reachable by long-distance underwater infrastructures. In the light of these findings, we investigate the structure of the Internet's long haul connectivity. We propose a new methodology to identify long-haul links in popular traceroute measurements. We apply it to a 7-year traceroute dataset finding relevant characteristics which have not been described before; the presence of ultra long-haul links and super routers

Biography: Esteban Carisimo is a Postdoctoral Researcher at AquaLab, a group in the Department of Computer Science at Northwestern University. His research focuses on diverse aspects of the Internet topology, including IXPs, CDNs, transit diversity, network congestion and interdisciplinary approaches to these topics. Prior to joining Northwestern, he obtained Doctoral (2020) and Engineering (2014) degrees from Universidad de Buenos Aires, where he was also appointed as Adjunct Professor at the Department of Computer Science of the School of Engineering between 2020 and 2021.
