Resilient SDN Intercontroller Network Design under Availability Requirements and Geodiversity Constraints

In Software-Defined Networking (SDN), the data plane is defined by the switches which are connected to a set of controllers defining the control plane. The intercontroller connections have lacked the same focus in the literature as the switch-controller connections, despite the set of logically centralized controllers being the brain of the SDN network. In this paper, we address a bi-objective joi...
