Abstract:
Distributed control plane solutions are adopted in large SDN-controlled networks, to improve control plane scalability. Many studies exist, on Controller Placement or Selection Problem (CPP/CSP) using different optimization criteria. Most of them consider static solutions to optimize controller placement. However, in a dynamic context, (i.e., traffic flows variation, possible failures of links, nodes, or controllers, etc.) the initial controller placement and controller-to-forwarders mapping could be no more optimum. Additionally, in practice, the controllers have limited processing capacity so, their overload is possible. A solution for the above problems could be a partial dynamic switch migration, e.g., when detecting some controllers’ overload. The contribution of this work-in-progress paper is an enhancement proposal of a dynamic migration solution (recently proposed in the literature), by introducing a multiple condition-aware migration complex decision. The proposed approach could solve the trade-offs between different optimization objectives of the network operator.
