An Autonomic QoE-Aware Management Architecture for Software-Defined Networking

Context-oriented computing has introduced new challenges in Quality of Service (QoS) management since the diversity of applications, forms of access and the TCP/IP architecture model make it difficult to provide services aware of Quality of Experience (QoE). In view of that, we propose an autonomous architecture of service provision and delivery that is QoE aware. The proposed components were designed and validated in a Software-Defined Networking environment. The results demonstrate that the solution is able to collect and infer the user's experience; map the QoS parameters in QoE to predict the Mean Opinion Score, and act autonomously to adjust the resources in the underlying network infrastructure, avoiding degradation of QoE.
