RE: NIM BoF

Eric,

In addition to the model you refer to (G.805/G.853.1), ITU has an
Access Network Transport (ANT) model that would be valuable. I hope
they've also developed a Transit Network Model (TNT) or whatever they
might call it. The ANT model is mostly of interest to L1, but it
serves to locate the reference points. Ditto for the (alleged) TNT.

But the usual problem is lack of open access to ITU documents. If the
IETF NIM BoF/WG is to benefit from their work, we must have that
access. Can you request permission from ITU or the authors to share
the G.853.1/G.805 model?

I think this is a good idea to take into account the work done within
TINA
based on ODP viewpoints. I did not follow the discussion on
information and
data, but I do believe that information maps on informational ODP
viewpoint
and data maps on Engineering viewpoint. An important work has also be
undertaken within ITU-T SG4/Q.18 (series G.85x) for the transport
network
management. It should be useful to consider the model G.853.1
described
following the ODP information viewpoint. This model is based on G.805
concepts and is very similar to the NRIM model developped by TINA.

There is also a book explaining all these concepts : Achieving Global
Information Networking

	Andrea,

	I agree with Joan Cucchiara's statement at this morning's NIM BoF
session in
	regard to the need to explicate the NIM concepts and model within
the
	general context of protocol development. To be more specific about
what is
	meant by "protocol", I refer you to the following two works:

	Elements of Network Protocol Design, by Mohamed G. Gouda (Wiley,
1998)

http://www.amazon.com/exec/obidos/ASIN/0471197440/o/qid=965232112/sr=2-2/102
-9323651-8129762

	Object-Oriented Network Protocols, by Stefan Boecking
(Addison-Wesley, 2000)

http://www.amazon.com/exec/obidos/ASIN/0201177897/qid%3D965232523/102-932365
1-8129762

	I also suggest that you list the modeling work of TINA
(Telecommunications
	Information Networking Architecture) and ODP in your slides for the
sake of
	completeness. There are five models in TINA/ODP that the group
should be
	aware of: enterprise/business, informational, computational,
engineering,
	technology. It may be valuable to compare/contrast these five models
to the
	two types of models discussed this morning: information and data.
(I'm going
	from memory here, so perhaps someone from TINA/ODP can correct me if
I've
	named the models incorrectly.)
