George Nomikos, FORTH-ICS

George Nomikos is a research engineer in INSPIRE group in FORTH-ICS, in Greece (http://www.inspire.edu.gr/) since June 2014. His main research interests primarily include Internet routing, Internet topology and network security. His main target is to better understand how the Internet ecosystem evolves, to track the Internet topology in the AS-, IXP- and Facility- level and evaluate the network performance under security constraints. To that end, George focuses on organising and creating advanced networking measurements and simulations, using analytical tools like graph theoretic approaches, social-driven heuristics and modeling traffic characteristics. In addition to the research activity, he is responsible for network and system administrative management like building solid and flexible server based systems and resolving issues related to networking anomalies, especially in routing and server-side application configurations.
Abstract: Internet eXchange Points (IXP) are critical components of the Internet
infrastructure that affect its performance, evolution, security and economics. In
this work, we introduce techniques to augment the well-known traceroute
tool with the capability of identifying if and where exactly IXPs are crossed in endto-end paths. Knowing this information can help end-users have more transparency over how their traffic flows in the Internet. Our tool, called traIXroute, exploits data from the PeeringDB (PDB) and the Packet Clearing House (PCH) about IXP IP addresses of BGP routers, IXP members, and IXP prefixes. We show that the used data are both rich, i.e., we find 12,716 IP addresses of BGP routers in 460 IXPs, and mostly accurate, i.e., our validation shows 92-93% accuracy. In addition, 78.2% of the detected IXPs in our data are based on multiple diverse evidence and therefore help have higher confidence on the detected IXPs than when relying solely on IXP prefixes. To demonstrate the utility of our tool, we use it to show that one out of five paths in our data cross an IXP and that paths do not normally cross more than a single IXP, as it is expected based on the valley-free model about Internet policies. Furthermore, although the top IXPs both in terms of paths and members are located in Europe, US IXPs attract many more paths than their number of members indicates.
