• Introduction
  Network virtualization (NV) is a transformative technology that abstracts physical network resources into virtual entities, enabling more efficient, flexible, and scalable network management. NV separates hardware from software, creating virtual networks that operate independently of the underlying physical infrastructure. This approach is critical in modern IT environments, especially in data centers, cloud computing, and software-defined networking (SDN).

What is Network Virtualization? Network virtualization involves combining hardware and software resources into a single virtual network or splitting a single physical network into multiple isolated networks. This abstraction allows administrators to create, configure, and manage networks through software instead of physical hardware. Virtual networks can mimic the features and functions of traditional networks, including routers, switches, and firewalls, but are more dynamic and flexible.
