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....
The constant evolution and growth of multimedia applications supported by today's mobile devices leads to an increase on the demand for video based services which impose new requirements in terms of bitrate and delay. In order to face these challenges, LTE appears as a technology capable of dealing with the video traffic load on mobile networks. However, given the inherent nature of mobile networks...
In this paper, the quality of experience (QoE) of real-time video streaming over long term evolution (LTE) networks is investigated. Network QoE metrics are proposed in order to capture the overall performance of radio resource management algorithms in terms of video quality perceived by the end users. Thus, real time video streaming over both the uplink (UL) and downlink (DL) directions is investigated,...
