Software-defined networking (SDN) is a promising way for offering efficient network management and future networks. The SDN consists of an intelligent configuration, better flexibility to integrate with various networks, communication and security technologies, and high-performance architecture. The SDN mainly consists of three layers, namely (1) the Infrastructure layer, (2) the Control layer, and (3) the Application layer. They are arranged as a stack on top of one another. Efficient data communication and data security are key components of various networks.S-Logix has taken various research works on the integration of SDN along with the IoT by utilizing blockchain, machine learning, and deep learning models to improve network security further
