Network Virtualization (NV) is the process of combining hardware and software network resources into a single, software-based administrative entity. In essence, it abstracts the physical network, allowing you to create multiple isolated virtual networks on top of a single physical infrastructure.

In networking, devices like routers and switches have distinct logical components that handle different tasks. These are broadly categorized into three planes: the management plane, the control plane, and the data plane. Understanding these planes is crucial for designing, managing, and troubleshooting modern networks.
