Hi Ron, et. al,
I’m in San Jose, if we can pull f2f. Otherwise, I’m available to a call at any time that works for the team.

                Regards,

Folks,

Can I ask the design team to meet urgently this week and come to one of the following conclusions? Either:


1)      We have complete consensus and it is ………

2)      We have complete consensus on A, B and C. We don’t have consensus on D, E, and F

3)      We can’t even agree on the questions

If the answer is 2), please be prepared to describe A, B, C, D, E and F at IETF 92. Also, be prepared to describe the rationale between opposing positions.

                                                                         Ron

Hi Qin, Ron, et. al,
apologies for the extended absence from the discussion.
I believe that the statement that:
> CFM like model as management plane model is orthogonal to data plane
> OAM protocol and meet all these requirements.
Does not entirely reflect state of discussion within the DT, especially that "CFM like model … meets all the requirements".

And I cannot agree with the conclusion here either:
> Also MP (assume that 'MP' stands for 'Maintenance Point') terminologies are widely used in the most of OAM technologies,
> it is not a good idea to define new terminologies to represent common
> elements for the OAM model.
It is not about luck of terminology but luck of terminology likely indicates that respective objects not being identified or used. Hence, if we to build common OAM model, objects should be identified and defined, including through terminology. Alternatively, we have OAM technologies that share sufficient commonality to work with.

        Regards,
                Greg

Qin,

Thanks for this summary. Unless I hear otherwise, I will assume that this is the group's consensus.

[Qin]: It has been a few days and no-one has disagreed.

IMHO, the design team has three tasks standing between itself and completion:

- craft a slide deck documenting findings

[Qin]: I will write the first draft and we can discuss on this list.

- present that slide deck at IETF 92

[Qin]: I am happy to do this if no one has objection.

- produce an ID recording findings

[Qin]: I can also start this task. I think I can make a first draft before Dallas, but I am not allowed to post it until Monday morning of IETF week in Dallas.

Is that OK?

Thanks.

Do we have volunteers for any of those tasks?

                                                                 Ron
