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.

 

Regards,

Ajoy

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
