“…Consequently, identifying the optimal quantity and placement of controllers to enhance performance and availability has become a core research challenge within SDN, often referred to as the controller placement problem (CPP) [11]. Distributing user requests across cluster controllers is vital to ensure a balanced distribution of workloads among them [12]. When aiming to reduce the overall response time for delegated tasks, careful attention must be paid to anticipating the necessary requirements for traffic volume and tools controlling service requests [13].…”

<p>In meeting the diverse and occasionally conflicting quality of service (QoS) requirements associated with modern communication networks, 5G technology has emerged as a pivotal player. In its architecture, 5G has adopted network function virtualization (NFV) and cloud-based approaches, aiming to simplify network and service deployment, operational processes, and management. The convergence of software defined networking (SDN) and NFV offers an effective solution, enabling scalable and high-performance 5G networks. However, this integration poses critical challenges, with the placement of SDN controllers being a central concern due to its significant impact on network performance, covering aspects such as latency, costs, and energy efficiency. This challenge is known as the controller placement problem (CPP). The central theme of this paper revolves around the intricate relationship between 5G core networks, virtualization technology, and the pressing concern of SDN controller placement, underscoring its significance in the modern networking landscape. We provide a survey of recent methodologies aimed at solving the CPP within the realm of SDN, with a particular focus on resiliency and high availability.</p>
