[ih] OSI and alternate reality

Catching up.

The core OSI Protocols were:
Ethernet (all 802 standards are ISO standards)
(Network Layer-was intended to be technology dependent and potentially non-standard. This is following the INWG and ISO 8648 model of internetworking.)
CLNP - as the internetwork protocol
TP4 for transport.
Fast-byte for the collapsed upper layers.
ACSE - for creating application connections including authentication and was designed to be recursive.
Then most anything that was proposed could be done (remember standards are bottom up, so if support could be generated for an application it could be done.) 

The application layer structure was designed to be modular, so base application protocols could be mixed and matched with supporting protocols. Among the things proposed were:
Virtual Terminal - which was mostly obsolete by then but was on the write track until DEC screwed it up.
FTAM - for file transfer
JTAM - for Job Transfer
CCR - for commitment, concurrency and recovery.
RPC - for Remote Procedure Call
TP - for Transaction Processing.
CMIP - for network management (but really the base application protocol since all application protocols act on objects external to the protocol. The only difference is what the object models are.)
