Abstract:
Software Defined Networking (SDN) is a recent networking technology that promises important advantages in IP networking, related to flexibility at network and application level, together with powerful management and control. However, the SDN specific centralization creates scalability problems in large network environments. Multi-controller implementation of the SDN control plane for large networks can solve the scalability and reliability issues introduced by the SDN centralized logical control principle. There are still open research issues 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 analysis of some solutions proposed in the literature followed by a work in progress, on multi-criteria optimization methods applicable to the controller placement problem.
