Software Defined Networking (SDN): centralized, programmable network management architecture.

Software Defined Networking (SDN) is an advanced networking architecture that decouples the control plane from the data plane, allowing for more flexible and efficient network management. SDN enables centralized control of network resources, which improves network agility and reduces operational costs.

7. Slide 1 Slide 2 Slide 3 Slide 4 Purpose of SDN To separate the network's control (brains) from the forwarding (muscle) functions. SDN is meant to improve the static architecture of traditional networks and may be employed to centralize network intelligence in one network component by disassociating the forwarding process of network packets (data plane) from the routing process (control plane).

8. Slide 1 Slide 2 Slide 3 Slide 4 Historical Background of SDN Monday, May 20, 2024 9 The history of SDN principles can be traced back to the separation of the control and data plane first used in public switched telephone networks. This provided a manner of simplifying provisioning and management years before the architecture was used in data networks.
