NFV and Secure Cognitive SDN for Educational Backbone Network Deployment

Abstract

Software defined networks (SDN) and wireless cognitive radio networks (CRN) are examined within the context of dynamic spectrum management. The features include control and data plane separation, centralized control, adopting open-source standards, programmability, quality of service (QoS) management, and security. The transformative impact of network function virtualization (NFV) is explored with a perspective on its architecture and applications in SDN, internet of things (IoT), cloud computing, and blockchain. The security aspect of SDN with specific focus on mitigating denial-of-service (DoS) attacks and vulnerabilities associated with open flow protocol is also addressed. The cognitive-inspired security mechanisms adapt to evolving threats integrating machine learning (ML) and artificial intelligence (AI) based algorithms for dynamic threat detection and mitigation exemplified through case studies. Adoption of software-defined perimeter, zero trust, blockchain, and quantum-safe cryptography in future are discussed. Finally, SDN applications for IoT networks are discussed.
