QoE-Aware Real-Time Multimedia Streaming in SD-WANs

The exponential increase in bandwidth-sensitive multimedia traffic on the net has given rise to new challenges and services. There is a need to have quality management measures to serve the high needs of efficient transmission and delivery in time-constrained environments over IP networks. Quality of Experience is one of the major techniques introduced to achieve the goals of application efficiency and user satisfaction from an end-user perspective. By utilizing crowdsourcing techniques, QoE becomes more cost-efficient and easier to measure. In this paper, we propose a framework that takes real time QoE feedback and forwards it to SD-WAN controllers in order to enhance streaming routes based on realtime user quality perceptions. We analyze how QoE can be affected by different streaming protocols and which streaming protocols perform better with imposing QoS quality changes.
