Question

In SDN, does the control overhead increase compared to the traditional network:

Answer 1

I think it does not. I assume that the control overhead gets minimized in the SDN as compared with the traditional network.

Software-defined networking or SDN is a kind of networking that offers many benefits for the networking services in network devices like routers and switches by separating the data plane and the control plane. The SDN has a centralized controller that determines the behavior of all the types of forwarding components that are present in the network. Also, many different approaches and programs are being identified to minimize the control overhead.
