    Quality of Experience

    We conduct research in relation to Internet applications: we evaluate applications, we model Internet applications. A frequently-performed investigation is the study of user satisfaction (Quality of Experience) with a particular Internet application.

    The workshop "Internet QoE" was successfully completed in Los Angeles @ UCLA. Four keynotes were given, a panel discussion was held, and 7 full papers were presented. Slides of the keynotes are available on request at <>.

    Current Projects

    SmartQoE (Measurement Concept and Trendscouting for QoE in Mobile Context)

    The focus of the project "SmartQoE" is on three major goals: 1. Development of a measurement concept to measure QoE-relevant application data with a smartphone app, 2. Analysis of collected data with respect to QoE criteria, 3. Trendscouting for QoE in mobile networks.

    DFG QoE-DZ (Analysis and Optimization of the Trade-off between QoE and Energy-Efficiency in Data Centers)

    This project focuses on quantifying and adjusting the trade-off between QoE and energy-efficiency in data centers for highly relevant use cases. An interesting use case for the interconnection between data centers, QoE, and energy-efficiency that is considered to have an increasing impact in the following years, are Virtual Desktop Infrastructures (VDIs). A VDI enables users to use very lightweight systems, e.g., so-called thin clients, whereby the actual operating system including all computations and software runs in a data center.

    Related Research Areas

    Research Area: YouTube Video Streaming

    YouTube is one of the most popular services in today’s Internet. It has more than 1 billion users and every day people watch hundreds of millions of hours of YouTube videos. Half of those YouTube views are on mobile devices. On the one hand, (mobile) operators want to handle the huge amount of video traffic as efficiently as possible (high revenue per bit), on the other hand, they want to deliver a high Quality of Experience (QoE) to satisfy their customers. Therefore, it is very important for operators to understand the performance of their networks with respect to YouTube traffic.
