[TUHS] ARPAnet now 4 nodes

[Dave Horsfall]

The ARPAnet reached four nodes on this day in 1969 (anyone know their 
names?); at least one "history" site reckoned the third node was connected 
in 1977 (and I'm still waiting for a reply to my correction).  Well, I can 
believe that perhaps there were only three left by then...

Hmmm...  According to my notes, the nodes were UCSB, UCLA, SRI, and Utah.

That's correct.  Although it was 1969.   I just sent Dave the paper from
the IEEE Annals of History of Computing:   1058-6180/15   [2015] Called
'The Production and Interpretation of APRANET Maps" by Fidler and Currie

I had commented on the ARPAnet's presence at UCSB on this list
earlier. Back then, being on the ARPAnet didn't mean anything
like what being on the Internet means now. Back then, only
a few research groups had access to, or even knew about, the
ARPAnet. I didn't find out about it until I was a grad student
there in the late '70s even though I had been an undergrad
from 73-75.

Has anyone put together a list of IMPs and dates in the order they were
added to the net?

Actually, I think if you go back far enough (1930's), it was part of UCB,
back when Lawrence first started it.

And of course the DoE didn't exist until 1977, so during the early ARPANET
era if would have been under the AEC, and then I assume the Energy Research
and Development Administration after 1974 (I assume it didn't go with the NRC
when the AEC was split up).

I really wonder how the CDC link worked.  The channels were electrically strange, and certainly not easily amenable to communicating with anything other than CDC controllers or perhaps a serial line through one of the front ends.

I did hear of a proposal at NADC around 1977 to try to hook into telnet and ftp from a CDC using some hack of the serial stuff.  The idea didn’t impress me: it would have taken a lot of hacking to get a kludge working.  It always took a lot to make CDC hardware play well with others.

Another clarification - LBL has never been part of UC Berkeley. It's
(always?) been a Department of Energy laboratory managed by the Univ.
of California. On the other hand, many people, due the close proximity
of LBL to UC Berkeley, have appointments at both places so it can
be hard to recognize which place somebody was working at when certain
research was done. For example, both Van Jacobson and Steve McCanne
had affiliations with LBL and UC Berkeley.

This page:
http://www2.lbl.gov/Publications/75th/files/exhibit.html

mentions 3 links between LBL and Arpanet:

- In 1974, the Lab’s CDC 6600 became the first online supercomputer when it was connected to ARPANET, the Internet’s predecessor.

- In 1986, when the Internet was on the verge of collapse from congestion, a Berkeley Lab researcher, Van Jacobson, co-developed the congestion control algorithms that allowed the Internet to keep growing.

- In 1995, Jacobson and Steven McCanne developed MBone, the first successful software for multiparty audio and video conferencing over the Internet.

I don’t think anybody was thinking you wilfully misrepresented things,
it is always interesting to hear about strands of history that might
have been missed earlier.

It would be helpful to better understand the time period, people
involved and the scope of work.

I’m a bit confused as to what time period you are referring to: I
think you are referring to the initial development of Arpanet, i.e.
the second half of the sixties. Is that correct?

There is a page here with some info on events in that period and it
may have missed some interesting development work done at LBL:

FWIW, I was actually at many of those meetings. (You can find my name in a lot
of those Meeting Notes.) Nobody from LBL, or UCB in general, was involved -
and the Meeting Notes (which, you will note, are quite detailed) indicate the
same thing.

(Later on, of course, Van Jacobson of LBL did some imporant work on TCP

    > Why would I misrepresent?   

Perhaps you are conflating several different things in your memory? Human
memory is very fallible, which is why historians prefer contemporary documents
(and even those sometimes have errors). Here:

  http://www.chiappa.net/~jnc/nontech/tmlotus.html

is a mildly amusing example (from a completely different arena) of all that.

I don't know about the historical record.  But everything I said is 
true, based on my own personal experience.
Why would I misrepresent?   I was there, this happened.  If people

I think this is incorrect. The "Birth of the Internet" plaque:

  http://ana-3.lcs.mit.edu/~jnc/history/BirthInternetL.jpg

mentions a number of organizations, but not UCB.

Also, if you look at early TCP/IP Meeting Notes, which list all the meeting

  http://www.postel.org/ien/txt/ien121.txt

(plus a bunch more only available in PDF form here:

  http://www.postel.org/ien/pdf
  
which I couldn't be bothered to look at, since they are huge scans which take
a while to download - see the IEN Index for the numbers) you won't find anyone
from UCB listed in any of them.

Berkeley did produce a now-common _implementation_ of TCP/IP, it's true, but
it had nothing to do with the "development" of TCP/IP.

This was looooong before Cliff Stoll.  I worked at LBL for 14 years, in 
the Computer Science & Applied Math (CSAM) group.   Don't remember the 
exact dates this was happening, but something like late 60s - early 
70s.   I remember discussing with Dennis Hall the report back to DARPA 
that emphasized no value for data transfer but high value for 
communications.   (Unfortunately, Dennis is gone now.) We even had a 
"demonstration" for DARPA.  However, the nodes we needed in a couple 
places weren't in those places yet, so we "simulated" a response by 
having something in, say, San Francisco receive an internet request, 
read it with their eyes, then type in a response.  ;-)    At least DARPA 
folks were told this was a simulation.

I'm also skeptical about this claim, although it could depend on
what "initial research" means. I believe LBL did work on early TCP
implementations, the conversion from NCP to TCP, and the early "software
tools" movement. (I was there for a year in 1988 and had the office next

LBL was part of UC Berkeley.  We were funded by DOE, who was working 
with DARPA.  But we were UC employees.  LBL had a contract with
DOE/DARPA to evaluate an early version of the the arpanet.  I was just 
getting started at that time, so only slightly involved.  The people I 
remember were Dennis Hall, Joe Sventek, Carl Quong & several other guys 
in EE.  A lot of the TCP/IP development was done at the Lab.

We also worked heavily with the CS people on campus.  I think this was 
before Kirk McKusick, Bill Joy, et al.

I was interested to find out more about this: I looked in Hafner, "Where
Wizards Stay Up Late" (the popular, but well-researched, book on the ARPANET)
but couldn't find 'Lawrence Berkeley' or 'LBL' in the index (although it did
have Lawrence Livermore); there were a couple of 'Californa, University of (at
Berkeley' listings, but none covered this. In Abbate, "Inventing the Internet"
(the first half of which covers the ARPANET), nothing under any of 'Lawrence
Berkeley', 'LBL', 'Berkeley' or 'California'.

In Norberg/O'Neill, "Transforming Computer Technology" (the standard ARPA
history, which has extensive coverage of the ARPANET project), there was one
entry for 'Californa, University (Berkeley)', which might be about the work
you refer to:

  "IPTO issued a contract for a 'network' project at the Berkeley campus of
  the University of California ... because of the presence at Berkeley of
  specialists in programming languages and heuristic programming".

But there's nothing about what was produced. Is there anything you can point
me at that provides more detail? Thanks!

No:

1977 was not too many years before the peak in size (with the MILNET split
coming in October, 1983). Per:

  http://www.chiappa.net/~jnc/tech/arpanet.html

"Prior to the split, in 1983, there were 113 IMPs in the ARPANET; after the
ARPANET/MILNET split, the MILNET consisted of 65 nodes, leaving the ARPANET
with 68 nodes."

Don't know about nodes, but the initial research on the arpanet was done 
at Lawrence Berkeley Lab.  The primary goal of the project
was for scientists to share data.  But, alas, the scientists didn't want 
to share data.  And, there were so many data formats that
nobody could read each other's anyway.  So we ranked the arpanet as a 
failure for that item.  However, we found that it seemed
to be incredibly useful for communications amongst people, i.e. email...

One of the original 4 was my Alma Mater, UC Santa Barbara. I can
