“…SDN is a networking paradigm that emerged in recent years via several initiatives and standards to ensure network flexibility, efficient utilization, cost-effectiveness, and innovation [1][2] [3]. Its design principle [4] is characterized by separating the control plane from the data plane through the provision of network programmability which brings about network dynamic configuration, control, and management simplicity [1] [5] [6]. In particular, the centralized control plane hides the complexity of the network to the application developer and delegates the underlying network control tasks to the controller.…”

“…Moreover, several SDN protocols have been developed such as ForCES, OpenFlow, HyperFlow, etc. with ForCes and OpenFlow being the most commonly implemented southbound protocols [1] [2] [3]. ForCes was initially declared the most efficient and dynamic southbound interface in the SDN as compared to OpenFlow.…”

“…Currently, the architecture of the SDN control plane has been designed with either a single controller or the distributed/multiple controllers [1][2] [9] [18][19][20]. These control architectures are further classified into physically or logically centralized and physically or logically distributed, each with several different controller types as shown in Fig.…”

“…However, having a single physically or logically centralized controller in charge of the forwarding nodes in a large-scale network constitutes a serious bottleneck to the network. It poses as a single point of failure that could leave the network with no intelligence, poor efficiency, unexpected high delays due to distance between controller and switches, lack of scalability support for large SDN networks, low controller processing power [1][2][3][6][7] [10]. These adversely impact the network performance and significantly limit the reliability, and availability of the entire networks [3] [11].…”

“…That is, any compromise on the network reliability will directly affect its availability due to failure which renders the controller or the network inaccessible. As leverage, multiple controllers have been proposed and introduced where more than one controller participate and work cooperatively in the forwarding decisions and the creation of multiple domains [1][2] [5]. In large-scale networks with multiple domains, several controllers are placed at different locations and assigned to monitor and control switches in each domain to enhance the network quality of service (QoS), traffic engineering, routing, fast failover [1] [2][5] [9] while ensuring that all controllers have the same global network view.…”

Software-Defined Networking (SDN) is a network paradigm introduced to overcome the inherent challenges of traditional networks. Its architecture is either deployed with a single controller or multiple controllers. While the first is not suitable for large-scale networks, the latter is confronted with a controller placement problem (CPP) in a large-scale network environment. CPP involves the challenge of deploying the optimal number of controllers within a network while meeting certain performance requirements considered conflicting in nature such as reliability, load balancing, latency, energy efficiency, and computation time. A single optimal or random placement may not be feasible in CPP and careful planning is of the essence to find an appropriate trade-off among the metrics. To achieve this, several CPP approaches have been proposed, developed, and deployed over the years, each having its unique objectives, strengths, and weaknesses. Therefore, this paper performed a comprehensive review of some of the existing approaches to identify the unique solutions offered, comprehend the different strategies and the challenges that exist as well as provide researchers with future directions aimed at improving the optimum location and allocation of controllers, in particular, for SDN application in wireless sensor network (WSN). The findings revealed several existing solutions and algorithms as well as several challenges such as the need for an efficient algorithm, attack-aware, cost-aware, and energy-aware CPP schemes while achieving a good quality of service.

Summary With the increasing number of Internet of Things (IoT) devices, current networking world is suffering in terms of management and operations with lack of IPv4 addresses leading to issues like network address translation (NAT) proliferation, security and quality of services. Software‐defined networking (SDN) and Internet Protocol version 6 (IPv6) are the new networking paradigms evolved to address related issues of legacy IPv4 networking. To adapt with global competitive environment and avoid all existing issues in legacy networking system, network service providers have to migrate their networks into IPv6 and SDN‐enabled networks. But immediate transformations of existing network are not viable due to several factors like higher cost of migration, lack of technical human resources, lack of standards and protocols during transitions, and many more. In this paper, we present the migration analysis for proper decision making of network transition in terms of customer demand, traffic engineering, and organizational strength with operation expenditure for network migration using evolutionary gaming approach. Joint migration to SDN‐enabled IPv6 network from game theoretic perspective is modeled and is validated using numerical results obtained from simulations. Our empirical analysis shows the evolutionary process of network migration while different internal and external factors in the organization affect the overall migration. Evolutionary game in migration planning is supportive in decision making for service providers to develop suitable strategy for their network migration. The proposed approach for migration decision making is mostly applicable to fairly sustained service providers who lack economics, regulation/policy, and resources strengths.

With the successful implementation of Software‐Defined Networking (SDN) in data center networking, the way forward for its deployment in the ISP/Telco network is becoming prominent. Small and medium‐sized networks may easily adopt SDN. The research on SDN deployment and implementation for a large‐scale network is continuing. This paper properly presents the current research status of Controller Placement Problem (CPP) and Multi‐CPP (MCPP) over SDN with their specific challenges and provides a comprehensive review of the major performance metrics, that is, latency, and controller load balancing techniques. This survey highlights the use of network partitioning‐based CPP and clustering approaches and their benefits in the context of SDN deployment. Moreover, this paper highlights the importance of implementing SDN and SDN security issues into ISP/Telco networks. Finally, we provide some key areas of ongoing research and discuss the future research direction regarding the various SDN‐based Controller Placement (CP) issues in the next‐generation IP and advanced networking technologies.
