It allows administrators to control the network, change configuration settings, provision resources, and increase network capacity — all from a centralized user interface, without the need for more hardware. As part of its enforcement efforts, OFAC publishes a list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. Software-defined networking (SDN) is a way to manage networks that separates the control plane (determines how packets should be forwarded) from the forwarding plane (moves packets from input to output). Placement on and Removal from the SDN List SDN moves the control plane that determines where to send traffic to software, and leaves the data plane that actually forwards the traffic in the hardware. An SDN may be involved in criminal activities such as terrorism, narcotics trafficking, or weapons proliferation. Montana State University has powered up intent-based networking and improved scalability with Cisco Software-Defined Access and Cisco Digital Network Architecture.
