Abstract
Software-defined networking (SDN) has introduced innovation to computer networks by shifting the intelligence to a control plane run by a controller. With SDN, the underlying networks become programmable and flexible, and innovative protocols are able to be tested. SDN is thus an excellent choice of infrastructure for 5G and beyond networks. Several controllers exist for the implementation of control logic in SDN. Hence, the comparison and performance evaluation of controllers is of great value for network engineers, end users and research communities. In this chapter, we investigate several state-of-the-art schemes for performance evaluation of SDN controllers and we compare their features. We also consider hybrid methods for the investigation of SDN controllers that combine feature and performance comparison. Finally, we compare the schemes with a proposed analytical network process approach for controller selection. We evaluate performance using several parameters demonstrated in Mininet.
