Web Quality of Experience from Encrypted Packets.

Pervasive encryption makes it hard for ISPs to manage their network. Yet, to avoid user churn at times of shrinking revenues, ISPs must be able to assess the quality of experience they are delivering to their customers. The case of the Web is particularly complex, with a plethora of recently proposed in-browser metrics that aim at capturing the page visual rendering quality (e.g. Above the Fold and SpeedIndex). In this demo, we showcase that such metrics can be estimated quite accurately just from streams of encrypted packets, using classic supervised learning techniques.
