fed. gov. had mandated elimination of the internet and forced move
to OSI (GOSIP) ... evident at interop '88 with lots of OSI products
... some poast posts
http://www.garlic.com/~lynn/subnetwork.html#interop88

the issue was that OSI didn't have any internetworking layer (either)
... basically would be reverting to the pre-tcp/ip era of the 70s

iso also had policy that none of the ISO network-related standards
bodies could standardize any protocol that didn't conform to the OSI
model.

to top it off, there were various references that ISO didn't actually
have requirement that ISO standards be implementable ... in contrast
IETF (aka internet) has requirement that there has to be at least two
interoperable (different) implementations to progress in the standards
process.

disclaimer: i was involved in taking HSP to X3S3.3 (us iso chartered
standards group responsbile for standards related to level3&4, aka
networking and transport) ... in the OSI model. some past posts
http://www.garlic.com/~lynn/subnetwork.html#xtphsp

it was rejected for violating the osi model ... at least

1) supported an internetworking layer that doesn't exist in iso
... non-existant layer that sits between bottom of layer4 and top of
layer3

2) went directly from transport to LAN/MAC interface ... bypassing
layer3/layer4 interface

3) went directly to LAN/MAC interface ... which doesn't exist in the OSI
model ... sits approximately somewhere in the middle of layer3 (more
than the link layer ... but not all ot the network layer).
