“…Accommodating the various UC efficiently in the same mobile communications infrastructure while ensuring a reduction in bandwidth requirements of fronthaul necessitated the restructuring and optimization of the architectural network [86]. NS concept allows the creation of logical networks that are service-customized by operators to ensure optimized and improved solutions such as functionality, performance, and isolation for various services with different requirements [87], [88]. In other words, NS is a network architecture that allows the logical networks (independent) and virtualized multiplexation on the same physical communication network infrastructure.…”

The mobile demands and future business context are anticipated to be resolved by the fifthgeneration (5G) of mobile communication systems. It is expected to provide an utterly mobile device, connected society, and support the demanding services of various use cases (UCs). This is intended to meet the demand requirement by providing services at tens of Gbps in terms of data rates, higher mobility range, lower latencies, and massive connectivity density devices per square kilometer. A comprehensive and up-todate survey of the different developed and proposed use cases is presented in this paper. The first part of the paper presents the overview of the new 5G Architecture by introducing new features such as the new radio interface (New Radio), an overview of the 5G Core Network, minimum requirements, and the Radio Access Network, 5G spectrum requirements and other fundamentals of the network. Secondly, a detailed review of the developed and proposed use cases for 5G communications by the standards development organizations (SDO) and other key players in mobile communication is provided. Thirdly, we went ahead to propose spectrum bands for the deployment of the various use cases based on the low-, mid-, and high-band spectrum and further classified the use cases with respect to their relevance and family, identifying the IMT-2020 test environments and the usage scenarios derived by the 3GPP, fourthly, the channel capacity and the bandwidth of the spectrum was studied, simulated and compared to ascertain the spectrum proposed in this paper for each UC family. Hence, this paper serves as a guideline for understanding the usage scenarios for the future 5G deployment in various environments. This would allow system developers to design and implement 5G channel characterization models specific to the usage scenarios to meet the system requirements.

“…To offer the implementation of network virtualization according to the diverse requirements of applications, SDN is an ideal platform through hypervisors such as Flowvisor, OpenVirteX, FlowN, and AutoVFlow [24]. The authors of [120] have focused on implementation of automatic network slicing for microservices, where open source software Node-RED is modified and extended to design IoT services for implementation. Open Air Interface platform and FlexRan controller are used for network slicing implementation of C-RAN for eMBB and IoT slices [110,121].…”

The emerging 5G applications and the connectivity of billions of devices have driven the investigation of multi-domain heterogeneous converged optical networks. To support emerging applications with their diverse quality of service requirements, network slicing has been proposed as a promising technology. Network virtualization is an enabler for network slicing, where the physical network can be partitioned into different configurable slices in the multi-domain heterogeneous converged optical networks. An efficient resource allocation mechanism for multiple virtual networks in network virtualization is one of the main challenges referred as virtual network embedding (VNE). This paper is a survey on the state-of-the-art works for the VNE problem towards multi-domain heterogeneous converged optical networks, providing the discussion on future research issues and challenges. In this paper, we describe VNE in multi-domain heterogeneous converged optical networks with enabling network orchestration technologies and analyze the literature about VNE algorithms with various network considerations for each network domain. The basic VNE problem with various motivations and performance metrics for general scenarios is discussed. A VNE algorithm taxonomy is presented and discussed by classifying the major VNE algorithms into three categories according to existing literature. We analyze and compare the attributes of algorithms such as node and link embedding methods, objectives, and network architecture, which can give a selection or baseline for future work of VNE. Finally, we explore some broader perspectives in future research issues and challenges on 5G scenario, field trail deployment, and machine learning-based algorithms.

“…Orchestration: BlueArch also supports ETSI MANO orchestration, Open Mano and RIFT.io orchestrators are hosted as VMs within a XEN environment. This supports orchestrating Virtual Network Functions (VNF) and leverage network slicing ability [20], [21] for optimal service and resource management. RIFT allows prebuilt VNFs to plug and play over the system, called onboarding.…”

In this paper, we've proposed BlueArch, a testbed for 5G research and experimentations. It is a customized setup, that comprises of several opensource components. It provides a platform to create and customize virtual network infrastructures and benchmarks prototypes. BlueArch provides high flexibility in terms of customization, configuration, and programmability. It supports 5G features such as softwarisation, virtualization, and orchestration etc. Furthermore, it offers use cases like IoT, MEC, and SDN through various modes such as simulation, emulation, access to physical network and interfacing with other testbeds. The goal of this paper is to present the structural and functional building blocks of BlueArch, along with their organization and implementation. Finally, three uses cases are also given with results, to demonstrate the functionalities.
