Abstract:
Large Software Defined Networks (SDN) solve the control scalability problem coming from the SDN control centralization principle, by defining and installing several regional controllers. Therefore, a controller placement problem (CPP) should be solved. During run-time, possible failures of links or node appear; then a forwarder node could try to select an available and reachable controller among those which are functional. This is called controller selection problem (CSP). Although many studies have been published, the above problems are still open research issues, given the various network contexts, providers’ policies and possible multiple, different optimization criteria. Therefore, multi-criteria decision algorithms can provide valuable solutions. This paper is based on a previous work which has developed a simulation model for multi-controller SDN network, targeting optimization while including resilience aspects of the controller placement problem and controller selection problem. The current paper extends that work, by including a more in-depth analysis, giving relevant examples and introducing additional novel experiment results.
