The Internet Engineering Task Force (IETF)
This is one of the main technical bodies. It is an international community of network designers, operators, vendors and researchers concerned with the development of the Internets architecture and its transport protocols such as IP. Significant sub-groups are the Internet Architecture Board, a technical advisory group of ISOC with a wide range of responsibilities and the Internet Engineering Steering Group, which is responsible for overseeing the activities of the IETF and the Internet standards process.
An interesting feature of the IETF, in common with the other organisations is that it operates using electronic communications as much possible, without recourse to meetings. The IETF has just three main meetings per year. New technical specifications are largely agreed through e-mail and discussion forums.
