Ajoy,
During IETF meeting our conclusion was to first create the
reference
model and use-case scenarios.
Ajoy->
Yes, I agree that we talked
about creating a reference model. But I think
before we
start creating a reference
model, we have to understand what kinds of information
we are
planning to exchange using L3 MIH protocol.
Unless we know the kinds of information,
it is
difficult to say if MIH entity
should be located at AP, AR or any other host on
the network.
Also, we may not be able to
agree how the messages should be exchanged.
It was evident
that we do not have a
common understanding on what we need to do in IETF.
Ajoy-> I
agree. I did raise this issue
during second conference call, but
I guess we
still decided to go to IETF
without cooking up our requirements.
The purpose of
tomorrow's call is to discuss this in details
and decide upon a
common framework. Once we have consensus with a reference model,
finding out
the requirements will be easier, IMHO
Ajoy->
But how can we have an agreement
on a reference model, unless we agree on
what is
intended use of L3 protocol.
. We have
captured all
the scenarios to discuss and scope it.
Ajoy->
This is exactly I am afraid of. See
if we start discussing all possible scenarios then
we will
never be able to focus on selected
few that is really important. That is why I am proposing that
all of us
come up with a scenario model that
they think is important and make a case for that.
Finally
based on concensus we can decide what
should be the final reference architecture.
I agree with you
that we need to discuss the information
elements as well before creating the requirements.
Ajoy->
Yup
On the other hand, we need to understand the IS reference model first
before generating the requirements.
Ajoy->
Please see my earlier comments.

Hi Subir et
al,
Your
scenarios are quite similar to what
have been discussed earlier. What are we trying to achieve out of next
conference call?
I would
suggest first let us discuss
various information elements that we would like L3 protocol to carry
before we
can
dive into
protocol requirements. The
choice of protocol will heavily depend upon the type of information we
want to
exchange using MIH
protocol.
Also, I am not sure producing
all permutations and combinations of protocol
scenarios
will enable us to achieve our
goal. It is unlikely that we can design a protocol that will cover all
possible
scenarios
that we can think of.

Attached is
an initial set of slides
that some of us have prepared after our
meeting/discussion in Paris IETF. Following is our
tentative agenda for
tomorrow's teleconference:
1) Discuss the Reference
model and Use-cases -
1hr and 30 mins
2) Next steps for IETF
requirements -- 30 mins
