A Survey of Controller Placement Problem in Software-Defined Networking [PDF]
IEEE Access, 2019 In order to simplify the management of the traditional network, software-defined networking (SDN) has been proposed as a promising paradigm shift that decouples control plane and data plane, providing programmability to configure the network.

The Equitable Controller Placement Problem
2023 13th International Workshop on Resilient Networks Design and Modeling (RNDM), 2023 Node-to-node connections refer to the links or channels that connect individual nodes (or devices) in a network. These connections allow nodes to communicate and exchange information with each other, forming a network of interconnected devices. To perform this function, nodes must have access to controllers-the devices (installed in selected node ...

The controller placement problem [PDF]
Proceedings of the first workshop on Hot topics in software defined networks, 2012 Network architectures such as Software-Defined Networks (SDNs) move the control logic off packet processing devices and onto external controllers. These network architectures with decoupled control planes open many unanswered questions regarding reliability, scalability, and performance when compared to more traditional purely distributed ...

Low failure recovery cost controller placement strategy in software defined networks
网络与信息安全学报, 2020 The controller placement is an important problem in software defined networks.Existing researches pay more attention to deploying controller planning for node failures and ignore the fact that the link failure can also effect the network drastically.To ...

The controller placement problem or the controller selection problem? [PDF]
Journal of Communications and Information Networks, 2017 In SDN, the control logic of packet processing devices is moved onto the SDN centralized controller. This decoupled networking architecture creates some critical concerns when compared to traditional distributed architectures. One primary concern in this architecture is the placement of the controller, which is commonly known as the CPP.

SDN Wireless Controller Placement Problem-The 4G LTE-U Case
IEEE Access, 2021 To cope with the shortage of available licensed spectrum, 4th Generation Long Term Evolution (4G LTE) is expected to be deployed also in the unlicensed spectrum. This raises the problem of the coexistence of multiple operators.
