Software defined networks bring many benefits with the centralization, application programmability interfaces and quick implementation of policies across whole network. Scalability and security are improved comparing with traditional networks, but centralized control have some drawbacks as it can be vulnerable for internal or external denial of service attacks. In this article, a comparison between two of the most used SDN controllers and the effect of internal denial of service attack towards the southbound interface during switch registration is presented. During the attack the CPU utilization and response time of the controller is collected and analyzed.
