“…In this system, dynamic flow routing is not implemented. Dynamic re-routing according to the bitrate of the video segments for dynamic adaptive HTTP streaming (DASH) clients is proposed in [5]. To provide quality adaptation, the video files having different quality representations are stored on the DASH server.…”

“…Commonly used QoE parameters are the received bitrate, percentage of lost packets, outage duration, number of quality changes and startup delay [2]. The routing algorithms for sending video packets over SDNs proposed in the literature aim to increase QoE parameters in terms of the received bitrate, outage duration and startup delay [3][4][5].…”

“…If the problem is in SDN network, then a different path is selected, otherwise the server is changed [17]. Path assignment by considering the bitrate of the segments and path capacities for increasing DASH clients' performance running over SDN networks is proposed in [18]. The server signals the controller to give information about the bitrate of the current segment and the paths are changed if the capacity of the current path is not enough to convey that segment packets.…”

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.

“…The type of encoder immensely influences QoE and is applicable for scalable video codecs (SVC) that inspect streaming using H.264/SVC with wavelet-based coding. Authors of [70,71,72,73,74] introduced a new approach to encode and segment video information for adaptively streaming H.264 video. They also achieved up to 30% reduction in encoding bitrate while maintaining the same or higher quality of video.…”

Streaming media systems such as YouTube, Netflix, and Apple Music are reining the multimedia world with frequent popularity among users. A key concern of quality perceived for video streaming applications over Internet is the Quality of Experience (QoE) that users experience. Due to changing network conditions, bit rate and initial delay, the multimedia file freezes or provides poor video quality to the end users. Researchers across industry and academia have explored HTTP Adaptive Streaming (HAS), which splits the video content into multiple segments and offers the clients varying qualities. The video player at the client side plays a vital role in buffer management and choosing the appropriate bit rate for each segment of video to be transmitted. A higher bit rate transmitted video pauses in between whereas, a lower bit rate video lacks in quality, requiring a tradeoff between them. The need of the hour was to adaptively vary bit rate and video quality to match the transmission media conditions. Furthermore, the main aim of this paper is to give an overview on the state of the art of HAS techniques across multimedia and networking domains. A detailed survey was conducted to analyze challenges and solutions in adaptive streaming algorithms, QoE, network protocols, buffering, etc. It also focuses on various challenges on QoE influence ISSN 1943-3581 2017 www.macrothink.org/npa 86 factors in a fluctuating network condition, which are often ignored in present HAS methodologies. Moreover, this survey will enable network and multimedia researchers a fair amount of understanding about the latest happenings of adaptive streaming and the necessary improvements that can be incorporated in future developments.
