IAB IAB The Internet Activities Board The origin of today's IAB lies in the Internet Configuration Control Board (ICCB), which was created in 1981 by Vint Cerf, at that time program manager at DARPA , to advise him on technical issues. The ICCB was chaired by David Clark, MIT. In September 1984, after the ICCB meeting held at RSRE in Malvern, UK, the ICCB was disbanded and replaced by the Internet Advisory Board (IAB). This change was initiated by Dave Clark and Barry Leiner, who had taken over management of the Internet research program at DARPA. The IAB consisted of the chairs of the newly-formed research task forces and Jon Postel (ISI), as RFC editor and "protocol czar". The first set of chairs of the task forces were the members of the ICCB. The IAB was chaired by Dave Clark.

Editor's Notes
- #2 Never has there been such dramatic changes to the business world as we have seen in the 1990’s with e-business and the internet. The role played by internet has forced companies to get connected to stay relevant so they may compete in today's fast moving markets. In the 60’s and 70’s there were many different networks, protocols and implementations. Sharing of information among these dissimilar networks soon became a problem. A common protocol needed to be developed. The Defense Advanced Research Projects Agency funded the exploration of this common protocol. The TCP/IP protocol suite evolved from the ARPANET protocol suite where the fundamental concept of layering was introduced.
