Re: Does TCP/IP "comform" to ISO/OSI?

Saying that something conforms to the OSI reference model is
essentially meaningless, so yes, TCP/IP does conform. The reference
model is the basic conceptual layering. You can use those layers to
analyze just about any protocol suite. What you're thinking of is the
ISO protocol suite. That's a specific set of protocols, and TCP/IP
doesn't follow it. As far as I can tell, vendor statements that their
(non-ISO) protocol follows the OSI reference model is almost entirely
hype. At best it means that the design is close enough to ISO that
eventual migration to the ISO protocols will be easier than with a
protocol suite that is very different in philosophy.
