Software-Defined Networking

Software Defined Networking (SDN) increases agility and reliability, while simultaneously reducing cost by decoupling the control plane from the forwarding plane, and allowing programmatic management of the control plane.

This allows near-instantaneous response of the network to changing traffic patterns, centralized management of the network, reduction of human error, faster provisioning for new users, and reduced dependence on expensive purpose-built hardware.  SDN can reduce capital cost by lessening dependencies on proprietary hardware and dedicated appliances.  Security can also be improved through the fine-grained control provided by SDN.
