COMMENT:
----------------------------------------------------------------------


I agree with Kathleen's discuss points and have one
more aspect to offer that I hope you include in that
discussion:

This model I think will lead designers to only think
about the nodes that are supposed to have access to
traffic.  (See also below about broadcast media.) The
model will generally not capture the reality that some
other nodes can also actually see or influence traffic
and I think that will lead to vulnerabilities not
being recognised. I don't have a good suggestion for
how to fix that problem but I do think you ought
mention it as a security consideration, e.g. something
like: "For models such as these - the real world
network may allow additional communications or links
that are not represented in the model and such links
may enable vulnerabilities that are liable to be
missed when considering only the model. These models
don't really capture the security or privacy aspects
of the network." 

- 4.2 and generally: It is not clear to me how to
represent broadcast media (e.g. radio) nor how IP
multicast would be reflected in this model. I assume
those can be done but as a bit of a hack.  

- nit: 6 authors and 4 contributors. I wish people
(esp chairs) would just enforce the 5 author guideline
and say why that's inappropriate in the few instances
in which that is the case.
