Software-Defined Networking (SDN) promises to enable vigorous innovation, through separation of the control plane from the data plane, and to enable novel forms of network management, through a controller that uses a global view to make globally-valid decisions. The design of SDN controllers creates novel challenges; much previous work has focussed on making them scalable, reliable, and efficient.

We argue that, to control a realistic network, we do not want one monolithic SDN controller. Instead, we want to compose the effects of many controller modules managing different aspects of the network, which may be competing for resources.
Each module will try to optimize one or more objectives; we address the challenge of how to coordinate between these modules to optimize an overall objective function. Our framework design, Corybantic, focusses on achieving both modular decomposition and maximizing the overall value delivered by the controller's decisions.
