Keywords: Software Defined Networking; Distributed Control Plane; Controller placement; Reliability; Multi-criteria optimizations

Abstract:
Multi-controller implementation of the Software Defined Networking (SDN) control plane for large networks environment can solve the scalability and reliability issues introduced by the centralized logical control principle of the SDN. However, there are still open research topics related to controllers placement, static or dynamic assignment of the network forwarding nodes to controllers, especially when network nodes/links and/or controllers failures appear or some constraints are imposed. This paper contains an analytical view of some solutions proposed in the literature followed by a work in progress, on multi-criteria optimization methods applicable to the controller placement problem.
