The Internet Engineering Task Force (IETF) is an open standards organization, which develops and promotes voluntary Internet standards, in particular the standards that comprise the Internet protocol suite (TCP/IP). It has no formal membership roster or membership requirements. All participants and managers are volunteers, though their work is usually funded by their employers or sponsors.
The IETF started out as an activity supported by the US federal government, but since 1993 it has operated as a standards-development function under the auspices of the Internet Society, an international membership-based non-profit organization.
