Which organization manages the development of the OpenFlow protocol?

The Open Networking Foundation (ONF) is responsible for managing the development of the OpenFlow protocol. The ONF was established to accelerate the adoption of Software-Defined Networking (SDN) and to promote standardization in this area, making it the authoritative body for OpenFlow, which plays a critical role in enabling network programmability through separation of the data plane and control plane.

Under the ONF's stewardship, OpenFlow has evolved to support various use cases and has partnered with other technologies to enhance network flexibility and efficiency. This positioning allows ONF to directly influence how OpenFlow develops, incorporating feedback from the industry to meet current and future networking needs, making it the go-to organization for OpenFlow protocol developments.

The other organizations listed, such as IEEE (Institute of Electrical and Electronics Engineers), CCITT (now known as ITU-T), and IETF (Internet Engineering Task Force), focus on broader networking standards and technologies but do not specifically manage OpenFlow's development. Therefore, while they play important roles in networking standards, they are not directly associated with OpenFlow.
