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.
