In a software-defined network the SDN Controller is the “brains” of the network.
It is the strategic control centre of the SDN network, relaying information to the network devices 'below' via southbound APIs and the applications and business logic running ‘above’ via northbound APIs

Zeetta Networks has extensive in-house expertise with the most popular open-source SDN controllers including ONOS™ and  OpenDaylight.

In addition, we have developed optical extensions for several controllers such as OX, POX, FlowVisor and OpenDaylight based on OpenFlow V1.0.

Zeetta's controller extensions include optical OpenFlow libraries for the device-to-network southbound abstraction layer, core controller modules to manage state of network, vendor specific feature integrated modules and a key virtualization engine which supports virtualization over packet, optical and IT nodes.
