Re: architected shim layers [was Re: threats ID]
Masataka, please moderate your language.
Moderate your language and never say layer 3.5 again.
I understand layering
well enough to know that the layers in the OSI model are very
I never say anything on OSI model.
In the Internet, layer 3 is connectionless whereas layer 4
maybe connection oriented.
and a better model would have been a recursive
one, with no predefined number of layers.
If you understand layering correctly, you should know that
internal of a layer is not visible from the adjacent
Recursive means some layer may have internal structure, which,
because of layering, is not visible from outside.
NAT is indeed a defective shim layer, but what this WG has been
mainly talking about is architecturally designed shims.
What some of the WG member has been talking about was
architecturally designed NAT. It failed, of course.
