[ih] Protocol numbers (was IP version 7)

[Barbara Denny]

The setup was in an enclosed vehicle if I am remembering right.  I don't think they wanted to leave a truck with the equipment unattended in the middle of nowhere.   I was mostly baby sitting.  I could 
monitor things like link connectivity, etc. and reboot the SINCGARS applique if things looked strangeor stopped working. I also would take notes about possible errors but I think this demo was uneventful in that regard.  I also think they did leave me with another radio in case I needed to talk to anyone.
During the last Packet Radio demo in Germany, we did use hummers and we still had barely enough room 
to add the LPR.

  Hi Barbara - just curious... What did they expect you to be able to *do* while sitting out there?   Debug code?  Install a patch?  Re-assemble the OS?   Balance a VT52 on the hood of a jeep?

 Too bad I didn't think of that when I was located in a vehicle in the middle of an Army reservation at Fort Bragg for an exercise. They decided they had better come get me. They were firing some live stuff. I think it was some form of gas but right now I don't recall exactly what.

   FYI - one of the other old-timers jogged my memory -- that Intrepid
 Internet Engineer on the Carl Vinson was Peter Cudhea.

 >> Besides ARPA/DARPA, I do think the Army was the biggest supporter of packet radio network research and testing at SRI, including enhancing the existing SINCGARS radio with modified packet radio protocols in a packet applique.  This prototype was done by SRI and ITT with people from their Fort Wayne,  Indiana location.  I do think this work may have lived on in some form in subsequent SINCGARS production contracts.  I never was in the loop for this part but I remember there was certainly lots of interest to do this. The Navy and Air Force projects were few and pretty much over with in the mid-80s at least at SRI if I remember correctly. (I wasn't involved in any Navy contracts involving packet radio so I don't know if they supported any efforts in this area).   CECOM at Fort Monmouth was the focal point for the funding and for the army personnel we worked with on the projects.  Paul Sass was one key person.
 >> I think the MATNET node might have already been installed on the Carl Vinson by the time of the SRI work . I am starting to have vague memories about some talk/drawings about how data could be gotten to and from the ship.   I think part of the equipment SRI installed on board was at least one Sun workstation on an ethernet.   We also had one person from SRI support a sailing from Alameda to Hawaii.   I hope my memory on this effort isn't too faulty.
 >> Barry Leiner returned to DARPA later and spearheaded  the Global Mobile Information Systems program (GloMo).  Things started happening in 1994  but I believe most of the research contracts started in 1995.  SRI had the SE&I contract for the program. I left SRI in 1996 so I wasn't around for the whole effort.
