CS402: Computer Communications and Networks

This video covers the historical significance of the IETF in shaping the Internet. The IETF's origins were as a network working group in the late 1960s, before the Advanced Research Projects Agency Network (ARPANET) implementation. Vint Cerf and Bob Kahn were instrumental in developing TCP/IP and transitioning ARPANET to TCP/IP in 1983. In 1986, the IETF's mission was to address engineering challenges within the DoD Internet, which included ARPANET and the Military Network (MILNET). The Internet Activities Board (IAB) transformed into the Internet Architecture Board (IAB) in 1992, which brought about changes in the roles of the Internet Engineering Steering Group (IESG) and the Internet Research Task Force (IRTF). There was controversy surrounding the IAB's recommendation of IP version 7 (IPv7), which led to the restructuring of the IETF and IAB through the POISED Working Group.
