Network virtualization is a technology that creates multiple software-defined virtual networks on top of physical network resources and runs them in isolation from one another. It is built on VLANs, overlay tunnels, and virtual switches (Open vSwitch), and it includes plugins such as Calico, which provides per-tenant networks to container environments, and experimental tools such as vrnetlab, which emulates network equipment in containers.
