<div dir="ltr">thanks Craig, I was going to point that out. DARPA paid for the BBN effort AND for the Berkeley effort.<div><br></div><div>Clem,</div><div><br></div><div>I see we are actually talking about two different aspects of the ascendance of TCP/IP.</div><div>I was speaking to the networking service angle, scaling and investment - NSF had a huge impact</div><div>in my opinion.</div><div><br></div><div>Commercialization of the equipment and software arose from a different thread:</div><div><br></div><div>1. IBM, Digital and HP all implemented TCP/IP on their commercial operating systems - but it was their Research Groups</div><div>who did that (I encouraged this).</div><div>2. I also encouraged the UNIX TCP/IP development at 3COM for which Metcalfe never forgave me because after</div><div>he implemented that offering, the Berkeley release came out for free</div><div>3. INTEROP made Internet visible to a much larger, non-academic audience, had training sessions and allowed</div><div>a lot of product vendors to demonstration the interoperability of their software/hardware - a major sales point </div><div>when you are trying to decide what to buy. </div><div>4. there were very few implementations of OSI and none that I know of were commercially successful</div><div>5. In 1992, NIST was persuaded to do an analysis of TCP/IP and OSI and concluded that it was OK</div><div>for government users to procure TCP/IP despite previous guidance to use OSI according to the</div><div>Government OSI Profile (GOSIP). </div><div>6. MOSAIC hits about 1993 followed by Netscape Communications and its IPO.</div><div>7. Cisco, Proteon and later, Juniper, produce commercial routers. Sun Microsystems produces Work stations and they</div><div>all use TCP/IP.</div><div>8. Novell tries to use IPX and XNS but just doesn't have the traction. </div><div><br></div><div>i don't think our views are necessarily at odds - but I am curious about your reaction to the 8 points above.</div><div><br></div><div>vint</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Feb 15, 2019 at 3:59 PM Craig Partridge <<a href="mailto:craig@tereschau.net">craig@tereschau.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Feb 15, 2019 at 12:23 PM Clem Cole <<a href="mailto:clemc@ccc.com" target="_blank">clemc@ccc.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><div style="font-family:arial,helvetica,sans-serif"><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Feb 14, 2019 at 2:58 PM Craig Partridge <<a href="mailto:craig@tereschau.net" target="_blank">craig@tereschau.net</a>> wrote:</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote"><div><br></div><div>Dennis' decision to adopt TCP/IP for NSFNET was critical. </div></div></div></blockquote><div style="font-family:arial,helvetica,sans-serif">Hmmm. It certainly did not hurt and I agree was cleafrly an amplifier and important. But I'm not sure that was as important as the basic economics of the time -> Moore's Law and cheap cycles (i.e. I don't think the NFSNET choice, while helped the effect, was not the high order bit on the success function).</div><div style="font-family:arial,helvetica,sans-serif"><br></div><div style="font-family:arial,helvetica,sans-serif">This was the time of the beginning of the workstation wars and the dominate OS was UNIX and in particular BSD which came with a known working IP stack (as I said, the USG paid to have that written by BBN).

I was the manager of the BBN UNIX TCP/IP effort after Rob Gurwitz left (I think Rob inherited it from Jack Haverty, but not sure). The BSD stack with sockets *was not written by BBN*. It was written by Bill Joy at Berkeley -- using the earlier BBN 4BSD code as a reference. Entirely new code, but originally bug-for-bug compatible (indeed, years later, when a bug was found in the BSD TCP, the BSD folks stood up and said "that's a bug from BBN").</div><div><br>Craig </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote"><div style="font-family:arial,helvetica,sans-serif"></div></div><div hspace="streak-pt-mark" style="max-height:1px"><img alt="" style="width: 0px; max-height: 0px; overflow: hidden;" src="https://mailfoogae.appspot.com/t?sender=aY2xlbWNAY2NjLmNvbQ%3D%3D&type=zerocontent&guid=42f724ad-a953-4d77-9be4-bf140328c494"><font color="#ffffff" size="1">ᐧ</font></div></div><div hspace="streak-pt-mark" style="max-height:1px"><img alt="" style="width: 0px; max-height: 0px; overflow: hidden;" src="https://mailfoogae.appspot.com/t?sender=aY2xlbWNAY2NjLmNvbQ%3D%3D&type=zerocontent&guid=f991f7a3-f67f-4933-a93d-0f2267c2866c"><font color="#ffffff" size="1">ᐧ</font></div>
