Scientific Trip: Visit to DUKAN-2 Water Treatment Plant
The Open Networking Foundation(ONF), a user-led organization dedicated to promotion and adoption of software-defined networking(SDN)manages the OpenFlow standard. ONF defines OpenFlow as the first standard communications interface defined between the control and forwarding layers of an SDN architecture. OpenFlow allows direct access to and manipulation of the forwarding plane of network devices such as switches and routers, both physical and virtual (hypervisor-based). It is the absence of an open interface to the forwarding plane that has led to the characterization of today’s networking devices as monolithic, closed, and mainframe-like. A protocol like OpenFlow is needed to move network control out of proprietary network switches and into control software that’s open source and locally managed.
