Since spring 2015, I am a PhD student at Queen Mary University of London (QMUL) under the supervision of Prof. Steve Uhlig and Dr. Félix Cuadrado. My research focuses on Internet measurements; more specifically, I am looking into infrastructures and distributed systems used for content delivery. In a recent study I managed to reveal the server infrastructure used by Netflix to deliver their video streaming services. The study not only describes the geographical server distribution and traffic estimation, but also exposes the huge number of different networks in which servers are deployed. Exposing the infrastructure in different networks contributes to a better understanding of the challenges faced by large-scale, Internet-wide distributed systems.
