“…Physical layer abstraction is required for both optical and radio resources of the converged network to achieve joint optimization of physical and virtual network resources at the NFV orchestrator level. Achieving the abstraction of all physical resources is a step towards achieving end-to-end network slicing and translating high-level O&M goals to technical parameters in beyond-5G networks, as seen in the efforts, such as [28,97].…”

Three convergent processes are likely to shape the future of the internet beyond-5G: The convergence of optical and millimeter wave radio networks to boost mobile internet capacity, the convergence of machine learning solutions and communication technologies, and the convergence of virtualized and programmable network management mechanisms towards fully integrated autonomic network resource management. The integration of network virtualization technologies creates the incentive to customize and dynamically manage the resources of a network, making network functions, and storage capabilities at the edge key resources similar to the available bandwidth in network communication channels. Aiming to understand the relationship between resource management, virtualization, and the dense 5G access and fronthaul with an emphasis on converged radio and optical communications, this article presents a review of how resource management solutions have dealt with optimizing millimeter wave radio and optical resources from an autonomic network management perspective. A research agenda is also proposed by identifying current state-of-the-art solutions and the need to shift all the convergent issues towards building an advanced resource management mechanism for beyond-5G.

“…A global view of the network is maintained at the SDN software-based controllers, which receive requests from the different applications and provide them with resources to guarantee the required quality of service. At the application layer, SDN involves network components to provide abstraction and supervision for a proper network configuration at any time, as well as orchestration and resource allocation [68].…”

5G Security Challenges and Solutions: A Review by OSI Layers

The Fifth Generation of Communication Networks (5G) envisions a broader range of services compared to previous generations, supporting an increased number of use cases and applications. The broader application domain leads to increase in consumer use and, in turn, increased hacker activity. Due to this chain of events, strong and efficient security measures are required to create a secure and trusted environment for users. In this paper, we provide an objective overview of 5G security issues and the existing and newly proposed technologies designed to secure the 5G environment. We categorize security technologies using Open Systems Interconnection (OSI) layers and, for each layer, we discuss vulnerabilities, threats, security solutions, challenges, gaps and open research issues. While we discuss all seven OSI layers, the most interesting findings are in layer one, the physical layer. In fact, compared to other layers, the physical layer between the base stations and users' device presents increased opportunities for attacks such as eavesdropping and data fabrication. However, no single OSI layer can stand on its own to provide proper security. All layers in the 5G must work together, providing their own unique technology in an effort to ensure security and integrity for 5G data.

“…This interface is used to ensure connectivity of different services and RAN interfaces to active phased array massive multiple input, multiple output (mMIMO) antennas in which beam forming/steering is performed with electrical or optical phase shifters. This work was later extended in [30] to integrate, on top of the SDN controller, an orchestration intelligence responsible for dynamically managing different slices through the optimization of the transmission parameters based on indicators such as traffic demand, network load and etc.…”

In this invited paper, we discuss how optical fibers, the de-facto choice for last-mile connectivity of radio access network equipment, can rise to the challenges of 5G. We start by addressing technologies and trends for pointto-point connectivity, from fully passive to auto-tunable wavelength division multiplexing. Then, we assess niche solutions based on point-to-multipoint optical connectivity and possible scenarios allowing fixed-mobile convergent topologies. Finally, we briefly exploit the potential of abstraction of optical and radio access equipment through software defined networking for intelligent and multi-tenancy ready traffic management compliant with the constraints of mobile interfaces and hosting locations of cloud infrastructures.
