Explanation Network virtualization encompasses logical isolated network segments that share the same physical infrastructure. Each segment operates independently and is logically separate from the other segments. Each network segment appears with its own privacy, security, independent set of policies, QoS levels, and independent routing paths. Here are some examples of network virtualization technologies: VLAN: Virtual local-area network VSAN: Virtual storage-area network VRF: Virtual routing and forwarding VPN: Virtual private network VPC: Virtual Port Channel
