Abstract:
For large networks SDN-controlled, distributed control plane solutions are proposed, to solve the scalability problems generated by the SDN control centralization principle. In a multi-controller environment, the Controller Placement Problem (CPP) should be solved. Additionally, in a dynamic networking context, including possible failures of links or nodes, a forwarder node could try to select an available and reachable controller among those alive. Although several studies have been published, the above problems are still open research issues, given the various network contexts, providers’ policies and possible multiple optimization criteria. Multi-criteria decision algorithms can provide valuable solutions. This paper extends a previous work, considering in the developed model some reliability aspects of the distributed SDN control and an extension to a dynamic controller selection method.
