Resource Management in SDN-Based Cloud and SDN-Based Fog Computing: Taxonomy Study

Abstract

Software-defined networks (SDN) is an evolution in networking field where the data plane is separated from the control plane and all the controlling and management tasks are deployed in a centralized controller. Due to its features regarding ease management, it is emerged in other fields such as cloud and fog computing in order to manage asymmetric communication across nodes, thus improving the performance and reducing the power consumption. This study focused on research that were conducted in SDN-based clouds and SDN-based fogs. It overviewed the important contributions in SDN clouds in terms of improving network performances and energy optimization. Moreover, state-of-the-art studies in SDN fogs are presented. The features, methods, environment, dataset, simulation tool and main contributions are highlighted. Finally, the open issues related to both SDN clouds and SDN fogs are defined and discussed.

Methodologies, Requirements, and Challenges of Cybersecurity Frameworks: A Review

“…Most business processes, such as design, implementation, establishment, purchase, manufacturing, investing, distribution, and after-sales services, now follow a completely digital workflow that spans multiple domains, connects multiple processes, applications, and equipment, and provides them with appropriate client data and their status, as shown in Figure 1. Convergence of available computing fields, such as the IoT, Software Defined Networking (SDN), and cloud computing, is intended to achieve this main goal, and everything-as-a-service and service-oriented paradigms were used to apply to CPSs with the help of automaticity and dynamic composition [37,38]. With software, service-centric models, data sharing, and multitenancy being pushed, this represents a revolution in the way systems are conceptualized, planned, developed, and operated.…”

“…Furthermore, the complexity of ICT infrastructures expands system vulnerabilities, encouraging the development of novel exploit methods to supplement existing traditional techniques such as distributed denial of service (DDoS) and botnets [4] and [5]. Even if they have been extensively developed and inserted into distributed systems, access control and identity management strategies cannot ensure the authenticity and trustworthiness of the entire series over time, nor can they track the dissemination of sensitive information and confidential material along the value stream [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Moreover, because the end user is often uninformed of the chain's topology and structure, determining if application providers, security techniques (e.g., encryption, integrity), and confidential strategies are compatible with his certain requirements is challenging.…”

Routing-Based Interference Mitigation in SDN Enabled Beyond 5G Communication Networks: A Comprehensive Survey

“…However, CRANs based spectrum management and interference mitigation can be further optimized through extension in input parameters by considering the backhaul capacity [120], mobility requirements [121], and multidimensional requirements [122]. Moreover, the presented scheme suggested a cloud-based SDN controller; however, SDN-enabled fog computing scenarios swiftly extend the performance of CR-based heterogeneous networks [123].…”

A Hybrid Software and Hardware SDN Simulation Testbed

“…This is relevant to our work as it advocates the simulation approach. The study in [ 17 ] discussed the taxonomy of utilizing asymmetric communication between network nodes with the end goal of improving performance and reducing the overall power consumption. This study was performed in the context of cloud and fog computing and several open issues related to SDN use cases were defined and discussed.…”
