I received an additional point...
Demonstration of
Compatibility (Done) From: Dove, Dan Sent: Friday, June 15, 2007 4:07 PM To: STDS-802-3-HSSG@listserv.ieee.org Subject: [HSSG] The List Folks,
I committed to
offering up my perspective on what has not been done (and should be done) in order to proceed with a 40G PAR in the
July timeframe.
This list is
subject to review, consideration, and revision if I have either missed
something or included something that does
not belong. Some of the determinations made are subjective, and you may
disagree with my conclusion. This is also worthy of discussion and resolution
via concensus. I have run it by people on
both sides of the discussion and made amendments per their feedback. If you
have additional feedback, please recognize that I am trying to be fair and
willing to consider your feedback.
When it is all said and done, this is *my* list and not
the HSSG's list. If the HSSG does not agree with me, then I will
gladly accept the consensus of the group. I based this on the history of
presentations and motions made in the HSSG and my experience working in 802.3
over the last 20+ years. There is no defined roadmap, but I think it should
help us to reach an agreement on how to proceed.
I should mention that when I say "Not Done"
relative to a motion, this means "not made and passed by a necessary
majority".
Motion to add 40G to HSSG Objectives (Not
Done)
Demonstration of
Broad Market Potential (Done)
Motion that HSSG has
demonstrated 40G Broad Market Potential (Not
Done)
Demonstration of Technical
Feasibility (Done)
Motion that HSSG has
demonstrated 40G Technical Feasibility (Not Done)
** Demonstration of Compatibility
(Done) (Not sure if a motion is
required on this or not.. might be addressed with acceptance of
criterion) Demonstration of Economic
Feasibility (Not Done)
-- 40G cost/performance vs 10G cost/performance (Done) -- 40G cost/performance vs 4x10G LAG
cost/performance (Incomplete)
-- I believe a good presentation on this subject
would show the relative performance of 40G to 4x10G LAG in quantitative
terms. The latency
comparison was a start, but please show how this
translates to protocol/system performance. I believe we need to see a
substantial performance benefit given the cost differential is
minimal. Motion that HSSG has
demonstrated 40G Economic Feasibility (Not Done)
Demonstration of
Distinct Identity (Not Done)
-- 40G PMDs distinct from 100G? (Done, then undone by OTN proposal) -- Show why the 2.5X cost/performance difference justifies
a project.
-- 40G functionally
distinct from 4x10G LAG? (Done)
-- How will the
HSSG address 40G 10Km and
40Km links and
would their addition undermine
distinct identity? (Not Done)
-- HSSG position on OTN rate and WAN PMD
(Not Done)
Motion that HSSG has demonstrated 40G Distinct Identity (Not
Done)
Motion
to Adopt 40G PAR proposal (Not
Done)
Motion
to Adopt compatibility
criterion proposal (Not Done)
Motion
to Adopt distinct identity
criterion proposal (Not Done)
Motion
to Adopttechnical feasibility
criterion proposal (Not Done)
Motion
to Adopt economic feasibility
criterion proposal (Not Done)
Motion
to Adopt broad market criterion
proposal (Not Done)
I hope at a minimum
that this clarifies my concern in Geneva that we were not ready to forward a 40G
PAR.
If there are any
remaining items to be completed to forward a 100G PAR, please respond with your
input as we should try to get both proposals
ready to forward for the July meeting. Since the
March meeting , I see no
additional work required beyond the formal motions needed to forward the
PAR.
