“…In order to realize the network slicing vision, an Orchestrator , a software responsible for automating the creation, monitoring and deployment of resources and services in the underlying softwarized and the virtualized environment is required. The ETSI defines two different types of orchestrators [208] : (a) Resource Orchestrator (RO) that coordinates, authorizes, releases and engages NFVI resources among different Point of Presence (PoPs) or within one PoP, and (b) Service Orchestrator (SO) -that creates E2E service between different VNFs). To date, many open source orchestrators have been developed to realize the dynamic network slices management and orchestration of resources in 5G networks.…”

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...

“…In addition to the technical aspects, economic and legal issues must be dealt within SLAs which get an increasingly important role [52]. These issues have been addressed by a number of fora, projects, and researches; see, for instance, [41,[53][54][55][56]. However, no overarching outcome is seen, and this is still a major research challenge that must be resolved before the vision of 5G becomes a reality.…”

The fifth generation (5G) of cellular networks promises to be a major step in the evolution of wireless technology. 5G is planned to be used in a very broad set of application scenarios. These scenarios have strict heterogeneous requirements that will be accomplished by enhancements on the radio access network and a collection of innovative wireless technologies. Softwarization technologies, such as Software-Defined Networking (SDN) and Network Function Virtualization (NFV), will play a key role in integrating these different technologies. Network slicing emerges as a cost-efficient solution for the implementation of the diverse 5G requirements and verticals. The 5G radio access and core networks will be based on a SDN/NFV infrastructure, which will be able to orchestrate the resources and control the network in order to efficiently and flexibly and with scalability provide network services. In this paper, we present the up-to-date status of the software-defined 5G radio access and core networks and a broad range of future research challenges on the orchestration and control aspects.

“…We refer to the use cases #1 and #3 as defined in [13] for more specific examples and descriptions. [23] In the next section, we discuss in more details the security requirements of the 5G multi-operator architecture and particularly, we will focus on the security of NFV and SDN as key enabler technologies for 5G. We consider the functional split of MdOs to provide a more detailed analysis.…”

The fifth generation of mobile networks (5G) will support new business and service models. A particular model of business and technical interest is multi-operator service orchestration, where service chains are created dynamically with coordination across multiple administrative domains. In such a scenario, resource sharing among operators is expected to be enabled by emerging network softwarization technologies such as Software-Defined Networking (SDN) and Network Functions Virtualization (NFV). On top of the inherent security issues of network softwarization, the complex relationships between operators add a unique dimension to the fundamental requirements for 5G networks. It is a key objective for network operators to identify new threats and security issues before deploying novel methods for service orchestration. This chapter elaborates on new security challenges posed by multi-operator service orchestration as defined by the H2020 5G-PPP 5G Exchange project. We revisit current standards and recommendations from ITU-T and ETSI under the scope of SDN and NFV. In addition, we present a method for threat analysis as well as gaps between requirements and current security schemes and standards, opening new research directions.
