[ih] "The First Router" on Jeopardy

[Barbara Denny]

 I went off to see what more I could find to check this timing out. Hope you don't mind me using myself in the search since that seemed easiest.   In the 1990s I took over a project involving the DARTnet testbed from Paul McKinney when he left SRI.  He had a paper at IEEE INFOCOM 1990 on SFQ (Stochastic Fairness Queuing). The conference was in June. In that paper,  he uses the term gateway. At the end of the project,  I submitted a technical report to the client on what I had done after he left SRI with SFQ. (In case you are interested,  I also did more work with an SFQ extension involving Virtual Clock. I had to use ST-II since RSVP didn't exist yet). This report was dated March 1993,  and I used the term router to describe the configuration.  
I was able to find a copy of my report online.

I am sure you can find a copy of Paul's IEEE INFOCOM paper.

 Alex,
  It is true that the CIX episode marked a trend in this direction, but 
there are two reasons why your specific suggestion is not right.

  First, by 1987, when both the ARPAnet and the proto-NSFnet backbone 
were both operational, networks that connected to both had to decide 
which to use, and that led to interesting routing decisions.  Problems 
encountered then led, for example, to creation of BGP.
  Similarly, again during the 1980s, a network might also connect to 
the NASA Science Internet and, again, have to make interesting routing 
choices.

  Second, recall that the initial CIX "exchange" was a single router 
with a T1 circuit from each of PSInet, Alternet, and CERFnet.  I don't 
know exactly how that router was configured, but note that it was that 
CIX router that had to make many of the interesting routing decisions.

  Also, I think that the term 'router' as a Level-3 gateway was in 
heavy use prior to 1991.

But I suspect it happened around the time the first CIX (Commercial Internet Exchange) agreement was reached.  Before that there was a "backbone" network (first ARPAnet and then NSFnet).  Packets went from your network to the backbone, across the backbone, and then to the destination network.  But after the CIX agreement there became a meaningful choice of routes, and the gateways had to start figuring out what the set of available routes was and choose one.  I understand this is an oversimplification of the internet structure, but I think it is a meaningful one.
