Newcomers' tutorial
This tutorial (1630-1730 UTC on 15 July 2018) provides introductions to a number of aspects of the Internet Engineering Task Force (IETF).
In addition to the Newcomers' training updated for each IETF meeting, Scott Bradner, who revised and presented this tutorial at the IETF for many years, produced a series of bite-sized IETF introductory videos specifically designed for online viewing for his Harvard University Extension School class. The Harvard Extension School graciously agreed to close caption the videos and let the IETF make them available for general viewing.
