Which is a benefit of controller-based networking?

A benefit of controller-based networking is increased security. When ACLs and filters are applied, they are applied informally to all nodes that are controlled by the controller. There is not a reduction of problems that can be encountered in a network with the introduction of controller-based networking. Throughput will not increase magically because of the introduction of controller-based networking. Complexity should be reduced with the introduction of controller-based networking because all of the configuration is centralized.
