How Network Virtualization Works 

Network virtualization operates by decoupling network resources and services from the underlying physical infrastructure, creating multiple virtual networks on a shared physical network.

A hypervisor or virtual switch runs on the physical network devices at the core of network virtualization. It creates and manages virtual network interfaces (VIFs) or virtual ports. Network virtualization software abstracts the physical network infrastructure, establishing logical virtual networks with unique resources such as IP addresses, subnets, VLANs, and routing tables.

Network overlays connect these virtual networks, encapsulating network packets with additional headers to traverse the physical network while maintaining isolation between virtual networks.

A central management system, often leveraging software-defined networking (SDN) controllers, helps manage and orchestrate the virtual networks, providing a unified view of configurations and policies.

By virtualizing the network infrastructure, organizations can achieve greater flexibility, scalability, and efficiency in network management, supporting the agile and cost-effective deployment of applications and services.
