Title

Internet Transparency and Neutrality

Abstract

The overarching theme of my talk will be Internet transparency. I will start from two fundamental questions: is it possible to infer a network’s neutrality based on external observations? is it possible to localise neutrality violations to specific network areas based on external observations? I will give the answers, then describe how we use them to reason about ISPs’ traditional traffic-differentiation practises (policing or shaping traffic from specific content providers). Then, I will argue that there is a more surreptitious (and more dangerous?) form of differentiation on the rise: in-network caching; and I will discuss whether caching — and the current Internet architecture, which relies heavily on it — is fundamentally incompatible with the concept of neutrality. I will close on a more fun note: how to improve Internet transparency by extracting thousands of Internet performance-metrics every day from public game-streaming footage.
