Is VLAN, VPN and SD-WAN part of network virtualization [closed]

Network Engineering

I have to make research about network virtualization. Here is my subject : Virtualization in networks: NFV (Network Function Virtualization), SDN (Software Defined Networks). In the topic, it only specifies NFV and SDN, but I was wondering if VPN, VLAN and SD-WAN could be considered network virtualization or not.

IP Conflict and VPN-Based Overlay Network Setup over WAN / VPN Solutions for Sites with Overlapping IP Address Ranges

Network Engineering

One of my biggest challenges here is determining how to establish an overlay network over the WAN. Another challenge is that the network infrastructures in SITE A and SITE B share the same IP blocks, and I cannot change them. How can I configure this network without causing any IP conflicts? 24 192.168.1.0/24
