I'm certainly not up-to-date on all or even many of the ISO
protocols, so I ask this.  TCP/IP has a number of very low-level
protocols such as BOOTP, TFTP, and so on.  It seems to my naive
knowledge that such protocols would be very difficult to do trivially
in OSI.  For example, it looks like ARP, BOOTP, and TFTP could
all comfortably fit in a smallish boot rom, whereas FTAM could
not reasonably be expected to do so.  My question is whether
I am right or wrong.  It seems that the lack of ability to
support such low-level protocols in OSI would mean either
two network standards (bad idea) or trivial special-case
versions of full-blown protocols (hard to standardize, I would
think) or massive configuration files requiring big boot roms or
local hard disks or whatever (expensive).  Is it really the case
that simple trivial applications are really difficult under OSI,
or have they just not been standardized, or have I just not
heard of them?     
		Just curious
