Abstract-This paper provides a brief overview and a vision for introducing a Quality of Experience (QoE) function for on-demand services or for premium users, based-on Software-Defined Networking (SDN). The proposed "QoE-service" can take advantage of the SDN global resource view and complementary QoE metrics to assure the desired performance for OTT applications by adopting traffic management mechanisms. This paper introduces the QoE-Service concept and SDN architecture and it presents a set of use cases that demonstrate its suitability and applicability to Long Term Evolution (LTE) networks. As Mobile Network Operators (MNOs) are facing a tremendous traffic increase due to the introduction of emerging mobile devices and applications, their revenue remains nearly constant [1] . OverThe-Top (OTT) providers, on the other hand, are gaining momentum with increasing revenues directly from users, while the MNOs that support these OTT services are not involved in such a revenue loop. This paper introduces the concept of "QoE-Service" (called QoEServ) enabling MNOs to offer enhanced OTT service performance upon request or for OTT premium users. QoE-Serv is an SDN-based function relying on a global network resource view, while considering particular QoS parameters (e.g., packet delay, loss rate, throughput, etc.) with respect to a specific application or user. QoE-Serv aims at providing an analysis on the selected application/service performance by mapping QoS measures to QoE and triggering traffic management mechanisms accordingly to assure QoE. In this way, QoE-Serv can enable operators to get into the revenue loop between OTT providers and subscribers, either by introducing a charging fee for this service or by offering it as an advanced feature for premium users. This paper provides the QoE-Serv vision, the supporting SDN architecture and a set of use cases demonstrating its applicability in LTE.
Liotou et al. REF introduced the framework of an SDN based QoE service to guarantee QoE level for on demand services of Over The Top (OTT) applications by monitoring network parameters via an SDN controller.
