Dear Lisa, NFV (Network Functions Virtualisation) and SDN (Software Defined Network) are just concepts. In my opinion, they are not competitive concepts, they are concepts which complement themselves.
There are many projects which establish different architectures for both concepts. Check here -> https://www.sdxcentral.com/directory/nfv-sdn/open-source-projects/ Whatever scheme you follow, just remember to keep things to a minimum, since any additional complexity on the network equipment, will not only increase the response delay, but it will also make the debug and troubleshooting process more difficult. Also, what ever type of physical equipment you use, make sure their functions actually work and do not trust what the product brochure tells you. Not every Switch that claims to be OpenFlow Compliant, actually are. I wish you good luck in your endeavours!
