Summary: SDN plays a crucial role in data centers and wide-area networks, and a major challenge is to select appropriate controller locations and address latency issues between controllers and switches in a logically centralized architecture. A cross entropy-based approach is proposed to solve the Controller Placement Problem, which has been shown to achieve minimal propagation latency in various network scales and configurations with stable computation results.

Summary: Software-defined networking (SDN) is a successful architecture that separates the control plane from the data plane, allowing for centralized network monitoring and control. The problem of efficiently placing controllers in an SDN environment is known as the controller placement problem (CPP). In this paper, a novel algorithm called dynamic feedback algorithm for controller placement for SDN (DFBCPSDN) is developed and compared with the varna-based optimization (VBO) algorithm. Experimental results show that DFBCPSDN outperforms VBO in minimizing the total average latency of SDN in different topologies.

Summary: To address the complex topology changes in UAVs network and increasing data transmission needs, a useful paradigm is the combination of self-organizing and SDN. However, the position of the control node in SDN impacts the command transmission between the controller and relay nodes, determining the communication quality. In this study, a network construction called SDN-FANET is introduced, formulating the problem as a classical network center location model. A particle swarm algorithm based on graph theory is proposed to solve the problem, and simulation results demonstrate its better performance in terms of accuracy and stability compared to benchmarks, with faster convergence achieved through optimized initial particle positions.

Summary: Software-defined networking (SDN) was developed to simplify the management of computer networks by decoupling the control layer from the data layer. This paper proposes a binary linear programming model to achieve a trade-off between the setup cost and average latency of control packets in wide area networks (WAN). The model determines the type, place, and minimum number of required controllers based on switch locations, controller processing capacity, and setup cost. It reduces setup cost and average latency compared to previous methods, providing the lowest setup cost and minimum average latency in controller placement.

Summary: Software defined networking (SDN) is a promising alternative to traditional networks, providing advantages such as network management flexibility, network programmability, and guaranteeing application Quality-of-Service (QoS) requirements. This paper proposes a method to dynamically compute the optimal number of controllers, determine their optimal locations, and assign switches to controllers in order to minimize flow set delay. Experimental results using ONOS controller demonstrate significant improvement in network performance in terms of response time and resource utilization.

Summary: This paper addresses the issue of heterogeneous controller placement problem in software-defined networking (SDN), proposing a Secure-aware and QoS-guaranteed approach to minimize network delay, balance controller utilization, and reduce control plane fault rate. The method involves determining types and numbers of heterogeneous controllers dynamically for enhanced security, partitioning the network into subnets using K-means clustering, and improving genetic algorithms for controller placement to ensure Quality of Service (QoS). Simulation results demonstrate the effectiveness of the approach in reducing control plane faults, improving delay, and enhancing load balancing compared to existing methods.

Summary: Software Defined Networking (SDN) is a new network architecture that decouples the data plane from the control plane and centralizes the network topology logically, making it more agile than traditional networks. The single-controller SDN architecture is insufficient for large networks, leading to the proposal of a multi-controller architecture and the Controller Placement Problem (CPP). To minimize propagation latency in WAN, the Greedy Optimized K-means Algorithm (GOKA) is proposed, which divides the network into clusters, merges them greedily, and places a controller in each cluster using K-means algorithm. Experimental results show that GOKA outperforms other heuristic algorithms in terms of stability and solution quality, reducing propagation latency significantly.
