“…As pointed out by Sgambelluri et al [158] , apart from catering to the needs of future 5G services, 5GEx is positioned to overcome also the historical, technological and market fragmentation of the European telecommunications sector. Such a generic, open, and standardized offering of various connectivity modes supported with other 5G capabilities will enable the numerous small to medium-sized enterprises (SMEs) and content providers to differentiate and monetize their online content and application provision [159] . It is intuitively mentioning that the core element in the 5GEx infrastructure is a slice that efficiently serves 5G verticals by relying on lower-level 5GEx basic services and SDN/NFV techniques.…”

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...

Roam Like at Home' is a slogan used to express the new roaming regulation applied to the countries within the European Union. Since June 15th, 2017, mobile network subscribers of the network operators within the European Union can use mobile services in other European countries without having extra charges for it. Although almost all mobile subscribers within countries of the European Union benefits from the new roaming rule, many mobile service providers are yet to be adapted to this change. Therefore, those providers bear the burden of the cost for the inter-provider traffic. Moreover, the latency between subscribers and their operator specific content must be reduced in order to provide a roaming service 'like at home'. An emerging virtualization technology such as a Network Function Virtualization (NFV) sheds light on these challenges. This paper describes the concept of the mobile roaming service and our ongoing implementation work as a part of 5G-PPP 5GEx project which aims at localizing inter-provider mobile traffic within the virtualized network infrastructure.

5G requires a redesign of transport networks in order to feed the increasingly bandwidth hungry Radio Access Networks and to benefit of the performance/cost efficiency provided by the integration of both backhaul and fronthaul segments over the same transport substrate as well as the incorporation of Cloud RAN architectures. In addition, to increase its usage and costefficiency, this new transport network should allow simultaneous use by different tenants, e.g. MVNOs, OTTs, or vertical industries. This paper presents the 5G Transport Network architecture designed in the 5G-Crosshaul project to address this challenge. An SDN/NFV-based control plane has been designed that enables multi-tenancy through network slicing. The proposed solution allows for a flexible and efficient allocation of transport network resources (networking and computing) to multiple tenants by leveraging on widespread architectural frameworks for NFV (ETSI NFV) and SDN (e.g., Open Daylight and ONOS).
