QoE-Aware Service and Network Management for Video Streaming Thomas Zinner (University of Wurzburg)

Описание: Abstract: Today's consumer Internet traffic is transmitted on a best
effort basis without taking into account any quality requirements. The backbone and the wireless access networks lack service guarantees for the predominant consumer Internet traffic, with video streaming being responsible for 60% of the traffic share. As services rely on interconnected networks, service performance and thus user satisfaction depend on network performance. Consequently, it is of utmost importance to understand the relationships between user-perceived Quality of Experience (QoE), and network performance as described by Quality of Service (QoS) parameters.However, in general the network does neither
know which Internet applications it is carrying nor which quality
requirements have to be met. To be able to meet the demands of
applications and users in the network, QoE-aware service and network management is proposed which requires an information exchange between applications and network. From a conceptual perspective, this requires three basic research steps: modeling, monitoring, and optimization of QoE. The first part of this talk covers QoE management and monitoring approaches, while the second part highlights concrete examples in order to demonstrate how QoE-aware network and service management may improve
the user-perceived quality of video streaming. Biography: Thomas Zinner received his Diploma and Ph.D. degrees in computer science from the University of Würzburg, Germany, in 2007 and
2012, respectively. His habilitation thesis titled âPerformance
evaluation of novel network and application paradigms and management approachesâ was finished in 2017. He is heading the âNext Generation Networksâ Research Group at the Chair of Communication Networks, University of Wurzburg and has published more than 80 research papers in major conferences and journals, receiving six best paper and best student paper awards. His main research interests cover video streaming, QoE management, network softwarization and performance evaluation. Homepage:
