Recollections from the mists of time... January 1, 1983<br>
<br>
It was actually quite exciting for those of us who had been defining the protocols and building<br>
prototype implementations for roughly 5 years, to see TCP/IP really function in production.<br>
At the time, we of course had no idea of its ultimate impact on the world.<br>
<br>
I believe that the switchover was enforced by the ARPAnet operational organization, DCA,<br>
disabling the primary link used by the ARPAnet host-host protocol NCP. Link 1? I guess<br>
I could look it up.<br>

"I guess I count as the expert in this case, because I wrote the IMP<br>
code that enforced the transition. It was a simple packet filter based<br>
on packet type (NCP vs. IP), NCP packets were dropped. I also<br>
administered a host-by-host list of hosts that had received extensions<br>
for various reasons - the code allowed exemptions on a per-host basis."<span class="HOEnZb"><font color="#888888"><br>
