(do fundo do Baú, Milo Medin (NSO) enviou uma apresentação dele ao IETF 
sobre a "guerra de protocolos" (anexada...). Segue, como curiosidade

abraço

Sorry I couldn't join the call last month - I was traveling, but this 
topic brought up many old memories from the Protocol wars.  Yes, Energy 
and NASA had extensive DECNet networks, and believed the propaganda from 
DEC that it would create an "easy" transition path from DECNet to OSI, 
and in the process would get broad interoperability.  This was just an 
attempt to keep people on proprietary systems and networks longer, and 
likely get them into a semi-unique profile for OSI that would maintain 
vendor lock-in.

My team (and others in NASA, esp our friends at JPL) viewed TCP/IP as 
the right approach, and as the leader of the NASA Internet at the time, 
my sponsor at NASA HQ (Tony Villasenor) got me appointed to the Federal 
Internetworking Requirements Panel (FIRP), which was a cross agency 
working group to make a recommendation on which way the Federal 
Government should standardize for Internet technology, OSI or IP.    
Steve (Wolff), you probably remember that group...

I was surprised by how many people wanted to swallow the vendor's 
recommendations and discard IP at that time.  Some of the meetings were 
quite contentious, and at one point, I remember threatening that if the 
panel recommended only OSI, that I would write a dissent and send a 
letter to Sen. Jessie Helms (who was on one of the oversight committees) 
about how the USG was going to throw away US technology leadership and 
hand the future of communications to European companies.  :)

In the end, the panel recommended OSI and IP as co-standards, which of 
course meant the death of OSI as the deployment rate and 
effectiveness of the TCP/IP stack and Internet connectivity was growing 
at a huge rate relative to OSI (both the 1st and 2nd derivatives were 
positive).  The rest is history.

I gave a presentation at one of the 1994 IETF on the FIRP - it's gone 
from the IETF site but found a copy of my slides (attached).  I even 
remember telling a joke - "NASA is going to OSI, Mars and Pluto, though 
not necessarily in that order... "  Fun days indeed!

Thanks,
Milo
