“…De Cicco et al [7] propose a client-side algorithm which avoids on/off behavior until reaching the highest possible playback quality. However, while they focus on QoS fairness, the approach still faces such problems as heterogeneous user devices, thus the issue of achieving QoE fairness remains.…”

The user-centric management of networks and services focuses on the Quality of Experience (QoE) as perceived by the end user. In general, the goal is to maximize (or at least ensure an acceptable) QoE, while ensuring fairness among users, e.g., in terms of resource allocation and scheduling in shared systems. A problem arising in this context is that the notions of fairness commonly applied in the QoS domain do not translate well to the QoE domain. We have recently proposed a QoE fairness index F, which solves these issues. In this paper, we provide a detailed rationale for it, along with a thorough comparison of the proposed index and its properties against the most widely used QoS fairness indices, showing its advantages. We furthermore explore the potential uses of the index, in the context of QoE management and describe future research lines on this topic.

“…In the next simulations, we compare our algorithm with three HAS controllers proposed in the literature, namely: the Probe and Adapt (PANDA) algorithm also proposed in [16], which is a conservative rate-based controller, that aims at having constant bitrate selection; the ELASTIC algorithm proposed in [17], which is a very aggressive buffer-based controller that strives to fully utilize the channel; and a conventional HAS controller as described and implemented in [16], which offers somehow an intermediary behavior compared to the other two. We investigate the performance of our algorithm for different number of N users sharing a bottleneck link.…”

Price-Based Controller for Utility-Aware HTTP Adaptive Streaming

HTTP Adaptive Streaming (HAS) permits to efficiently deliver video to multiple heterogenous users in a fully distributed way. This might however lead to unfair bandwidth utilization among HAS users. Therefore, network-assisted HAS systems have been proposed where network elements operate alongside with the clients adaptation logic for improving users satisfaction. However, current solutions rely on the assumption that network elements have full knowledge of the network status, which is not always realistic. In this work, we rather propose a practical network-assisted HAS system where the network elements infer the network link congestion using measurements collected from the client endpoints, the congestion level signal is then used by the clients to optimize their video data requests. Our novel controller maximizes the overall users satisfaction and the clients share the available bandwidth fairly from a utility perspective, as demonstrated by simulation results obtained on a network simulator.keywords-HTTP adaptive streaming, Pricing and resource allocation

“…This parameter can be measured bandwidth [10,11] or the level of buffer fullness [12]. Some client algorithms use both of them to decide representation [13].…”

Abstract-Today, the most of the video streaming system provides quality adaptation and prefers to send their packets over HTTP. MPEG group has standardized Dynamic Adaptive HTTP Streaming (DASH) regarding this tendency on the adaptive HTTP streaming. Besides providing quality adaptation with a non-scalable codec, DASH standard also allows Scalable Video Coding (SVC) to adapt quality. Software Defined Networks (SDN) is a recently emerged networking paradigm. SDN enables to separate control and data plane of computer networks and hence provides flexibility to network operators to implement their own routing approaches. In this paper, we propose a system for increasing Quality of Experience (QoE) of SVC-DASH clients by utilizing SDN. Our experimental results show that the proposed system provides an increase in received video quality and decrease in outage duration and startup delay when compared to the performance of the client running over todays Internet implementing shortest path routing.
