2019 arXiv   pre-print
Thus, we apply the data plane fault tolerance approach in SDN to improve the QoE of DASH clients in the case of congestion as well as the failure.  ...  To this end, we explore the change in Quality of Experience (QoE) caused by link failures under different cases using Dynamic Adaptive Streaming over HTTP (DASH) for video streaming.  ...  On the other hand, this is the first study that applies a fault tolerance approach to improve QoE in case a network-based problem like congestion.  ...
