Abstract

Network Virtualization (NV) and Software-Defined Networking (SDN) are two pivotal innovations that transform the way networks are designed, managed, and scaled. SDN provides a centralized control layer to manage and optimize network resources, while Network Virtualization allows for the creation of multiple virtual networks over a shared physical infrastructure. Together, these technologies enable a more flexible, scalable, and efficient network infrastructure that can meet the demands of modern applications and services. This paper explores the synergy between SDN and Network Virtualization, emphasizing how SDN enhances the capabilities of NV by providing centralized control, automation, and programmability. It also addresses the challenges of integrating these two technologies, such as network security, performance optimization, and the need for robust orchestration mechanisms. The paper concludes by highlighting the benefits of combining SDN and NV and suggests potential research directions for further exploration.
