Research Area: YouTube Video Streaming

We deal within the CAN group with the research field "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.

We investigate the properties of the video streaming.
We offer tools for the analysis of the play behavior and define QoE models.
