IETF - Internet Engineering Task Force

Definition

The Internet Engineering Task Force (IETF) is a large international community of network designers, operators, vendors, and researchers focused on the evolution of the internet architecture and its operation. It plays a crucial role in developing and promoting voluntary internet standards and protocols, including those related to Software Defined Networking (SDN) and OpenFlow. The work of the IETF is primarily organized into working groups that focus on specific areas of technology, ensuring that the internet remains robust and adaptable to new challenges.
