Yes, it's interesting to fill in gaps in the History.  I'm wondering 
about the evolution of the ICCB/IAB over the years.  I was on the ICCB 
from its inception until mid-1983, but don't know anything about its 
later history as the IAB.

Through 1983, the ICCB was focussed on planning and prioritizing work 
towards the "January 1983" Internet, tasked to be one capable of 
handling heavy loads.  It wasn't just technical issues, although there 
were plenty of those.  Some had to be addressed before 1983 to create an 
operational Internet as a service, while others were classed as ongoing 
research topics since there was no consensus on any particular solution 
but lots of ideas to pursue.

Most of the ICCB members were leading various Internet-related projects 
in their respective organizations, and would leave quarterly ICCB 
meetings with appropriate "marching orders" for their projects.

But several of the ICCB members at that time were from other parts of 
the US DoD (not ARPA where Vint was), and likely dealt also with 
administrative or political tasks, such as getting TCP to become a DoD 
Standard, causing NBS/NIST certification procedures for TCP to be 
created so thaat government contractors and auditors could verify that 
they had implemented TCP, orchestrating the NCP/TCP cutover to occur on 
ARPANET, and undoubtedly many other non-technical activities that had to 
happen for the Internet to grow and expand and become a reliable 
communications service.

My impression is that the role of the ICCB changed significantly over 
the years after it became the IAB, and its focus evolved to become 
almost purely technical.  But I don't know much at all about that part 
of the History.

Anybody remember more?
