What does the acronym SDN stand for?

The acronym SDN stands for Software Defined Networking. This approach to networking allows for more flexible and efficient management of network resources through software-based solutions rather than traditional hardware-based configurations. In SDN, the control plane (which makes decisions about how data packets should be handled) is decoupled from the data plane (which forwards traffic to the selected destination). This separation allows for centralized control and programmability of the network, providing significant advantages in automation, scaling, and network resource allocation. Software Defined Networking has been increasingly adopted in various environments, enhancing the capabilities of data centers and improving overall network management.
