OpenFlow v1.2 Specification (Dec. 2011)
OpenFlowÂ® is the first standard communications interface defined between the control and forwarding layers of an SDN architecture. OpenFlowÂ® allows direct access to and manipulation of the forwarding plane of network devices such as switches and routers, both physical and virtual (hypervisor-based).
OpenFlow-based SDN technologies enable IT to address the high-bandwidth, dynamic nature of today's applications, adapt the network to ever-changing business needs, and significantly reduce operations and management complexity.
For historical information about the origins of OpenFlowÂ® at Stanford University prior to the creation of ONF, please see archive.openflow.org.
