“…The need to improve the end users' experience together with the emergence of technologies such as SDN, MEC and personalized network slicing [46], which enable such improvements through service/application and user/OTT differentiation, pose a challenge to net neutrality principles. The QoE-SDN APP offers a differentiated and enhanced experience to the users of VSPs that choose to adopt it, in a broad sense.…”

While video streaming has dominated the Internet traffic, Video Service Providers (VSPs) compete on how to assure the best Quality of Experience (QoE) to their customers. HTTP Adaptive Streaming (HAS) has become the de facto way that helps VSPs work-around potential network bottlenecks that inevitably cause stallings. However, HAS-alone cannot guarantee a seamless viewing experience, since this highly relies on the Mobile Network Operators' (MNOs) infrastructure and evolving network conditions. Software-Defined Networking (SDN) has brought new perspectives to this traditional paradigm where VSPs and MNOs are isolated, allowing the latter to open their network for more flexible, service-oriented programmability. This paper takes advantage of recent standardization trends in SDN and proposes a programmable QoE-SDN APP, enabling network exposure feedback from MNOs to VSPs towards network-aware video segment selection and caching, in the context of HAS. The video selection problem is formulated using Knapsack optimization and relaxed to partial sub-problems that provide segment encodings that can mitigate stallings. Furthermore, a mobility prediction mechanism based on the SLAW model is introduced, towards proactive segment caching.

a b s t r a c tThe increasing consumption of multimedia services and the demand of high-quality services from customers has triggered a fundamental change in how we administer networks in terms of abstraction, separation, and mapping of forwarding, control and management aspects of services. The industry and the academia are embracing 5G as the future network capable to support next generation vertical applications with different service requirements. To realize this vision in 5G network, the physical network has to be sliced into multiple isolated logical networks of varying sizes and structures which are dedicated to different types of services based on their requirements with different characteristics and requirements (e.g., a slice for massive IoT devices, smartphones or autonomous cars, etc.). Softwarization using Software-Defined Networking (SDN) and Network Function Virtualization (NFV)in 5G networks are expected to fill the void of programmable control and management of network resources.In this paper, we provide a comprehensive review and updated solutions related to 5G network slicing using SDN and NFV. Firstly, we present 5G service quality and business requirements followed by a description of 5G network softwarization and slicing paradigms including essential concepts, history and different use cases. Secondly, we provide a tutorial of 5G network slicing technology enablers including SDN, NFV, MEC, cloud/Fog computing, network hypervisors, virtual machines & containers. Thidly, we comprehensively survey different industrial initiatives and projects that are pushing forward the adoption of SDN and NFV in accelerating 5G network slicing. A comparison of various 5G architectural approaches in terms of practical implementations, technology adoptions and deployment strategies is presented. Moreover, we provide a discussion on various open source orchestrators and proof of concepts representing industrial contribution. The work also investigates the standardization efforts in 5G networks regarding network slicing and softwarization. Additionally, the article presents the management and orchestration of network slices in a single domain followed by a comprehensive survey of management and orchestration approaches in 5G network slicing across multiple domains while supporting multiple tenants. Furthermore, we highlight the future challenges and research directions regarding network softwarization and slicing using SDN and NFV in 5G networks.Crown (A .A . Barakabitze). tems [1,2,3] . The increasing number of smart devices (e.g., tablets and smartphones) and the growing number of bandwidth-hungry mobile applications (e.g., live video streaming, online video gaming) which demand higher spectral efficiency than that of 4G systems are posing significant challenges in 5G. The Cisco Visual Networking Index (VNI) Forecast [4] predicts that IP video traffic will be 82% of all consumer Internet traffic by 2022, up from 75% in 2017. Mobile video traffic alone will account for 78% of the global mobile data traffic. W...

“…Examples of recent efforts to influence the design of 5G mobile networks utilizing network function virtualization can be found. 12,13,14,15 Control operations, typically carried out in network elements, decide the type of packet processing that is needed such as forwarding, modifying, or dropping packets. The SDN principle modifies the control plane by separating the network control plane functionality from the forwarding elements such as routers and switches.…”

SummaryThe evolved packet core (EPC) network is the mobile network standardized by the 3rd Generation Partnership Project and represents the recent evolution of mobile networks providing high-speed data rates and on-demand connectivity services.Software-defined networking (SDN) is recently gaining momentum in network research as a new generation networking technique. An SDN-based EPC is expected to introduce gains to the EPC control plane architecture in terms of simplified, and perhaps even software-based, vendor independent infrastructure nodes. In this paper, we propose a novel SDN-based EPC architecture along with the protocollevel detailed implementation and provide a mechanism for identifying information fields exchanged between SDN-EPC entities that maintains correct functionality with minimal impact on the conventional design. Furthermore, we present the first comprehensive network performance evaluation for the SDN-based EPC versus the conventional EPC and provide a comparative analysis of 2 networks performances identifying potential bottlenecks and performance issues. The evaluation focuses on 2 network control operations, namely, the S1-handover and registration operations, taking into account several factors, and assessing performance metrics such as end-to-end delay (E2ED) for completion of the respective control operation, and EPC nodes utilization figures.
