In a software-defined network, the data plane handles packets under the direction of a control plane, but the controllers are just applications that can run on standard x86 hardware. SDN controllers use a standard protocol (OpenFlow) to communicate with data plane devices. Other specialized network appliances -- like firewalls and load balancers -- that get recast as SDN applications also run on standard x86 hardware using the SDN controller to get the data plane devices to do what they need to do.
