"Internet Transparency"

( MPI-SWS talk in Kooperation mit dem Fachbereich Informatik)

The Internet was meant to be neutral: treat all traffic the same, without discriminating in favor of specific apps, sites, or services. As commercial interests threaten this ideal, many countries have introduced neutrality regulations. Unfortunately, none of them are actually enforceable. In this talk, I will first discuss the challenge of inferring whether a network is neutral or not using solely external observations. Then, I will show that we can go beyond neutrality inference and reach network transparency, in which networks provide explicit hints that enable their users to reliably assess network behavior, including neutrality. Network transparency, however, requires exposing information about what traffic is seen where and when, which can hurt user privacy. I will close by looking at the important question of whether network transparency indeed must come at the cost of reduced anonymity for Internet users.

Bio: Katerina is an associate professor of computer science at EPFL, where she does research on network architecture and systems, with a particular interest in network transparency and neutrality. She received an IRTF applied networking research prize (2020) and Best Paper awards at SOSP (2009) and NSDI (2014), all shared with her students and co-authors. She has been honored with the EuroSys Jochen Liedtke Young Researcher Award (2016) and three teaching awards at EPFL. Prior to EPFL, she worked at Arista Networks from day one, and received her PhD from Stanford (2007).
