Dear Ragnar,
in your email you are saying “During the discussion on May 1st at least one supporter of this document
stated clearly that the outcome of this document would not change their mind about TDD vs ACT”. Who do you mean? There are only two supporters/authors on the document. Both Gumersindo and I can change our minds in the presence of good arguments. Any
other interpretation of what has been said is a misunderstanding/misinterpretation.
Furthermore you write “I also heard at least one supporter of this document questioning if this document would change the mind of other individuals in the Task Force.” We sincerely apologize if
more listeners had the same mishearing as you did. Part of what we believe makes a good engineer is the capability to change his/her mind in the presence of good arguments and we believe that the dm group consists of many very capable engineers. What would
be the sense of striving for a comparison document otherwise?
Thank you for giving us the reason to clarify this to the group.
Kind regards,
Kirsten

Betreff: [802.3_ISAAC] [EXTERNAL] RE: Invitation to the 802.3dm comparison study
Hi Gumersindo, Do I understand correctly that you are giving people 2-3 working days to send in “criteria deemed important”? Is this a hard cut-off date? I see
that you talk about discussing “criteria fulfillment”. Can you please elaborate on

Hi Gumersindo,
Do I understand correctly that you are giving people 2-3 working days to send in “criteria deemed important”? Is this a hard cut-off date?
I see that you talk about discussing “criteria fulfillment”. Can you please elaborate on what this discussion will output?
During the discussion in New Orleans, you clarified that this work would result in input into the Task Force and was not an attempt to circumvent the Task Force. However, I see that your presentation
on the New Orleans meeting page has not been updated to reflect what you presented:
https://www.ieee802.org/3/dm/public/0525/index.html. Can you please clarify who will be the target audience of this document? If it is the Task Force, do you believe that the Task Force lacks
clarity on what it is trying to achieve?
How will disagreement be handled in in the discussion of this document? What kind of majority will be needed to put something into the document? Who makes the final call on what is in the output
document?
In your list on slide 7 of the New Orleans presentation I see things like “Bi-directional use of ports”. In my mind it is obvious that we will have traffic in both directions on the link. Are
you suggesting there that there should be a link that only goes in one direction, without any data flow in the other direction? Would you agree that this would be out of scope for the project?
Talking about things that are out of scope, in the Study Group there was majority support for including data rates above 10Gbps, but not the necessary 75% support for it. Would considerations
about extending the data rates above 10Gbps be in scope for your document?
Like I said in the New Orleans meeting, I am not sure what the value of this document will be for the Task Force. I worry that this will be a distraction for the Task Force without delivering
any tangible benefits. During the discussion on May 1st at least one supporter of this document stated clearly that the outcome of this document would not change their mind about TDD vs ACT. I also heard at least one supporter of this document questioning
if this document would change the mind of other individuals in the Task Force. If even the proponents of this document are saying that this document is not likely to change their mind, would it not make more sense for the Task Force to focus on its objectives?
Ragnar

Dear 802.3dm participants,
As announced on both the May 1st and May 16th 802.3dm interim meetings, here are the details for the next steps on our joint comparison study.
- In the first step, we would like to agree on a list of criteria to address before discussing the fulfillment of any criteria. In the attachment
you find a PROPOSAL for the comparison criteria and their metrics. Please take careful look at them and evaluate if additional criteria or metrics are needed.
- Send us your updated list (if any) until May 26th EOB. We know this is short notice, however, this only identifies the criteria
deemed important and not their fulfillment – for which we will then dedicate more time.
- We start on May 28th 15:00 CET with a Kick-Off meeting.
- Introduce a proposal for the structure for the final document which shall result from our efforts.
- Check on the collected criteria and discuss the collected input.
- Next steps on the proposed items to elaborate fulfillment details.
- Starting on June 4th we would then initiate a weekly series till July 23rd. Each week we discuss criteria fulfillment
based on the incoming proposals shared with the group prior to the meetings.
- Step by step completion/creation of the comparison document.
If you would like to participate in this meeting, please reply to either me or Kirsten (Kirsten.matheus@xxxxxx) and you will receive a dedicated meeting
invite (Teams-Link) or just join with the following link at the dedicated time:

You are welcome to send your input on the comparison items also if you are not able to join the meeting.
We are looking forward to your responses.
Thank you and best regards.
Gumersindo Veloso
P.s: For those not present at the last meetings, this is the motivation:
- Currently, two technical proposals are competing within IEEE 802.3dm.
- This documents aims to compare the two proposals and their rationales in order to provide an overview on the key properties and the different opinions on them.
- It may serve as a “technically qualified overview at a glance” reference for individuals wanting to understand and form their own opinion.
- The intention with this comparison document is
- to clarify where there are agreements and disagreements.
- to make the disagreements understandable.
- This document
- does not present a unified opinion.
- does not favor one proposal over the other.
- The authors prepare this document with the best intention to present an unbiased reference.
