What is OpenFlow?
OpenFlow is a communications protocol that allows remote access of a network to a network switch or router’s forwarding plane. Controllers are separate from switches. It was initially defined as the communication protocol in SDN architectures that allowed the SDN controller to communicate directly with the forwarding plane, which consists of network devices such as switches and routers, both physical and virtual (hypervisor-based), so it is more responsive to changing business requirements.
Why Do We Need OpenFlow?
OpenFlow originally defined the communication protocol in SDN architectures, allowing the SDN controller to interact directly with the forwarding plane of network devices such as switches and routers, both physical and virtual (hypervisor-based), allowing it to better adapt to changing business requirements. Division of hardware and software, control plane and forwarding, and physical and logical settings.
OpenFlow vs NETCONF
OpenFlow provides controllers of the network to determine the flow of network packets over a network of switches. Controllers are separate from switches. The Internet Engineering Task Force created and standardized the NETCONF network management protocol. NETCONF offers processes for installing, modifying, and deleting network device configurations.
