Question

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

 1.Depends on application and network topology

 2.Yes, always

 3.Not at all

 4.Depends on OpenFlow protocol

Answer 1

The answer is Option 1.

In SDN, the control overhead increase compared to the traditional network depends on application and network topology.

There are many benefits of using Software Defined Networks (SDN) as it separates the data plane from the control plane. Microcontroller architecture is an important feature of an SDN.
