DDoS attacks on SDN networks can create a single point of failure that has the potential to disrupt the overall network performance. In a single controller scheme, there is a potential risk of experiencing buffer overload, leading to traffic congestion as switches must wait for responses from the controller before forwarding network packets. To address this challenge, this research implements security measures using a multi-controller and load balancer approach, aiming to enhance SDN network resilience against DDoS attacks. The system operates by distributing the workload from the main controller to a backup controller through a load balancer when indications of a DDoS attack are detected. These attack indications are determined based on the miss rate value of unique forwarding requests exceeding a specific threshold. The results of this approach have proven effective in improving the reliability, responsiveness, and quality of SDN network traffic during DDoS attacks. The testing parameters involved in this research include controller response time and network traffic quality, comprising latency, bandwidth, throughput, and jitter. Based on the test results, the multi-controller and load balancer-based approach successfully enhanced network quality and controller responsiveness by 66.51% compared to the longer single controller scenario, specifically 202.49% during DDoS attacks. In terms of controller responsiveness, there is a very slight increase of around 0.01% in latency between the two. While Multi Controller demonstrated a remarkable 43.21% increase in throughput compared to Single Controller, this improvement in throughput is accompanied by a significant 204% increase in jitter.

“…Alguns artigos, são focados em alterar o protocolo OpenFlow, outros em adicionar middleboxes na rede (SPOONER; ZHU, 2016;HA;KIM, 2016). No entanto, é importante ressaltar que ainda existem muitos problemas de segurança para que a SDN seja confiável e robusta em produção (PRATHIMA et al, 2019).…”

As Redes Deﬁnidas por Software (Software Deﬁned Networks, ou SDN) constituem um paradigma para o desenvolvimento de pesquisas em redes de computadores que vem ganhando a atenção de grande parte da comunidade acadêmica e da indústria. No entanto, essas redes ainda apresentam muitos desafios operacionais e de pesquisa. Diante desse cenário, o presente trabalho investiga os componentes de um sistema de rede definida por software com qual obteve como principal resultado, a apresentação de uma visão geral sobre novas abordagens e a identificação dos principais desafios de pesquisas em andamento que podem contribuir para o avanço das SDN.

Software defined networking (SDN) can be understood as a software control system, built over a centralized system that controls a network's forwarding rule. SDN can be used in an enterprise, in a data center, or even in a household. It was the solution to one of the biggest problems when at times we had to do the manual configuration of all the devices. SDN has not only made networks easier to manage but it has also made it secure. SDN is based on logical centralization that again brings a wide range of challenging scenarios related to security threats. So, there is a need to bring a new way to address this problem. In this paper, we embrace a thorough overview of the latest works that applies security to SDN, proposed an advanced secure software defined network architecture and then, evaluated its performance with the existing models using mininet tool.
