Re: [BP] [bp] 802.3 approves Backplane Ethernet PAR
Yong,
802.3 did not vote to split the PAR. Rather, per the direction given by the Backplane Ethernet Study Group, we...
(1) ...presented a PAR, 5 Criteria, and Objectives list for the Physical Layer aspects of Backplane Ethernet, and these were approved by 802.3.
(2) ...requested that a new Study Group be formed to look into Layer 2 enhancements. The purpose of this Study Group is to generate a new PAR, 5 Criteria, and Objectives specific to Layer 2 enhancements. The question of whether this new study group should have been preceded by a CFI was a point of discussion in 802.3. In part, it depends on your view of whether the original CFI for Backplane Ethernet "covered" Layer 2 enhancements or not.
The vote taken within the BESG was to form a new Study Group, and not initiate a new CFI. No motion is necessary to initiate a CFI. Rather, interested parties can submit a request to a have CFI at the next WG plenary (35 day advance notice is required). At the closing plenary session, those parties may wish to request that 802.3 form a new Study Group. That request comes in the form of a motion much like the one the BESG recommended I put before 802.3.
Thank you,
-Adam

Dear Adam,
Thanks for your detailed (and I am sure time consuming)
response. This helps a lot. I am puzzled though on your item
2 subpart c): New study group needing simple majority.
IF this is new study group THEN
802.3 Operating Rule 4.2 - Formation - CFI scheduled
35 days prior to WG Plenary.
ELSE IF this is not a new study group but a split THEN
???
ENDIF
If I were to fill in ???, all my prior .3 experience, a vote
to split a PAR (close one I could remember was 1G copper, and
exactly not the same) was NOT simple procedural (and no separate
CFI was done to do the split). I recall the votes taken within
BP SG was to recommend a new study group, which requires 35 day
and CFI. Am I missing something? Please advise/clarify.
Thanks in advance for your efforts.
best regards,
Yong.

Yong,
My apologies for the delay in my reply.
First, if you would like a detailed account of closing plenary, I would
refer you to the plenary meeting minutes, which will be available at:
http://ieee802.org/3/minutes/index.html
I have been told the minutes from the March plenary meeting will be
posted later this week.
If you cannot wait for the minutes to be posted, you may also refer to
the Backplane Ethernet closing plenary report, which you can find posted
at:
http://ieee802.org/3/bladesg/public/mar04/closing_plenary_0304.pdf
In direct answer to your questions:
1. "please consider for approval under continuous process"
Information on the continuous processing can be found at:
http://standards.ieee.org/faqs/contproc.html
To summarize, the next meeting of the New Standards Committee (NesCom)
and the Standard Board is not until June. Under the regular process
this would be when our PAR is reviewed and the implication is that we
would not meet as a Task Force until the July plenary, at the earliest.
Under continuous processing, e-mail and the web are used to expedite to
process, giving us the chance of having our PAR approved in time for the
May interim meeting. The study group has requested to have the PAR
forwarded to NesCom for review. The addition of the "continuous
processing" phrase simply expedites that process.
2. Ammendments to Study Group Motions at the 802.3 closing plenary
session.
There were three changes made via motions to amend, which I will
enumerate below:
(a) Change the objective "Support BER of 1E-12" to "Support BER of
10^-12 or better".
The motion to amend passed unanimously (voice vote). This is superset
of the original objective. A solution that operates at exactly 1E-12
and a solution that operates at some BER below 1E-12 can both be
considered to have satisfied this objective. There was also some
confusion regarding scientific notation.
(b) Changes second bullet of Distinct Identity Criteria from "The
standard will define a single PHY for each speed for operation" to "The
standard will define at most one PHY for 1Gb/s operation and at most one
PHY for 10Gb/s operation" .
The motion to amend passed unanimously (voice vote). If I recall
correctly, the intent of the amendment was to allow for the possibility
of one PHY that supported both speeds.
(c) The motion to form a new study group for congestion management/rate
control was changed from "...for Layer 2 enhancements for congestion
management for Backplane Ethernet" to "...for Layer to enhancements for
congestion management including the needs of Backplane Ethernet".
Motion to amend passed Y:14,N:10,A:0. The amended motion passed:
23/18/15. Note that the motion to form a new study group is procedural,
and only requires a simple majority to pass. The needs of Backplane
Ethernet are considered in either form of the motion case. The
amendment was made in the interest of not limiting the solution to be
backplane-centric.
Thank you,
-Adam

Adam,
2nd message. I am still curious about what happened.
Would you enlighten me/us? Thanks.

Adam,
I am not clear on how the words in parenthesis got there, i.e.
"(please consider for approval under continuous process)". Also,
I had heard that some votes reversed study groups' votes that required
75% with mere 50% vote in 802.3. Would you clarify what happened during
the backplane Ethernet agenda in .3 closing plenary? Sorry, I had to
leave right before your agenda item to catch evening flight back.
best regards,
Yong.

Colleagues,
I am pleased to report that 802.3 voted to approve the PAR and forward
it to the SEC and NesCom. The motion:
802.3 WG approve the Backplane Ethernet PAR, as per par_0104.pdf, and
forward the PAR to the 802 SEC and NesCom for approval (please consider
for approval under continuous process).
TECHNICAL (75%)
Moved - A. Healey on behalf of the Study Group
Second - N/A
802.3 Voters (Y/N/A): 55/0/0
MOTION PASSES
Under continuous processing, there is a chance that our first Task Force
meeting will be in May. Even if this does not occur, we will still be
meeting as a Study Group. The meeting details are still being worked
out, but it will take place the week of May 24 in either Monterey or
Long Beach, CA. Meeting details and a work plan will be posted as soon
as they are available.
Thank you all for the great work.
Adam Healey
Chair, Backplane Ethernet Study Group
