 Sorry folks. That should have been USAREUR.  I have trouble keeping up with auto correction on my phone.
Happy Thanksgiving!

The Cisco AGS was released in May 1986 according to Wikipedia. I installed them in Germany for USAEUR probably in September of that year as best as I can recall.  I think the deployment first included IMPs but I think subsequently SRI removed the IMPs that were between the Cisco boxes (though I think IMPs we're called PSNs by this point in time. BBN certainly can chime in here).  I don't know about  SRI people using Cisco's AGS boxes for something like the bay area regional network.

 Hi Barbara,

I remember those cisco AGS boxes appeared at SRI sometime around the summer of 1986.  Some of the SRI staff who maintained them called them ‘routers’.  As time went on, that name stuck.  They may have provided access to BARRnet, the SF bay area NSFnet regional network.

I am using the final report for the Reconstitution Protocol project? to jog my memory.? ?I remember Jim Mathis telling me about this change in terminology because there was at least one other device, called a gateway, that provided a translation like functionality and people didn't want to create more confusion.? I also don't think we would have used the word gateway during the RP project if router was the accepted term when we started. I am pretty sure we also were using the AGS Cisco boxes? in? the fall of 1986 for a different SRI project so I think the change in naming was?underway by then. I don't remember feeling any surprise at Cisco's use of the word router to describe their product.
> It is interesting to remember that BGP as an experimental RFC wasn't released until 1989 so we still had the term gateway hanging around for quite a while afterwards.? I don't mean to ignore IGRP and EIGRP either. Then there is also Lixia Zhang's? paper on "How to Build a Gateway" dated April 1987.
