Interestingly, however, the SDN architecture, the actual realistic deployment methodology, does not have that same consensus. Some major network equipment vendors agree with the principles of SDN but want a distributed architecture whereby the intelligence is retained on the network devices and they could be controlled by a centralized orchestrator via vendor application programming interfaces (APIs).
