RE: [10GBASE-CX4] RE: [802.3] 10GBASE-CX4 Notice to IEEE 802.3




Dan,

I'm willing to wait until the Plenary to amend the 5 criteria, as I'm
sure that there will be some of that going on anyways.  I just wanted to
highlight my concern because the PAR is fairly specific, but the 5
criteria leave some question about the inclusion of UTP.  I didn't want
the CX4 group to be surprised if I stood up asking for an amendment.

Thanks,
Brad

Hi Brad,

I appreciate your concern. We may be a bit too general in our
description with the term copper media, but with regard to distinct
identity we are trying to demonstrate that there currently is only
a fiber-optic solution.

I realize that when 10GBASE-T comes in, your effort to provide 
distinction will have to be based not on your "copper media" type,
but upon the range, type of copper <UTP>, and perhaps solution
cost.

I have no problem addressing your concerns at our March Plenary if
it is acceptable to amend the 5 criteria at that time and just
update 802.3 to that effect.

Regards,

Dan

Upon first review of the PAR and 5 Criteria, my only concern is the use
of the term "copper media" with references to 10GFC and IB4x.  For those
that may not be familiar with those cables, "copper media" could infer
the inclusion of UTP copper media.  It would be my recommendation that
the 10GBASE-CX4 Study Group be a little more explicit in its reference
to the type of cabling, i.e. shielded copper media or shielded
twisted-pair copper media.

Thanks,
Brad

Dear Colleagues,

The 10GBASE-CX4 Study Group has been extremely busy over the last 4
months.
Since our CFI and the authorization of our study group, we have had
three
meetings and numerous teleconferences. As we described in our schedule
last
November, we have developed a PAR, 5 Criteria, Objectives and a working
paper so that we can get a specification developed in record time.

There has been a huge amount of consensus within the group on our
direction
and the working paper we have developed. Most votes have been unanimous
as
can be seen by reviewing our meeting content on the web.

Per our schedule, we have now a complete working paper. This document
has
been reviewed by the Study Group, improved, and detailed to meet our
objective of bringing it before the 802.3 Working Group for ballot if
our
PAR is approved. If our PAR is approved and our working paper is allowed
to
become a draft that goes out to ballot, we will have the opportunity to
perform two re-circulation ballots prior to the July Plenary. 

We were required to bring this document to 802.3 at least one week
before
the Plenary, but we are bringing it forward today, ahead of schedule, so
that you may have more time to review and provide feedback to our
reflector
at mailto:stds-802-3-10GBCX4@ieee.org. We intend to continue our review
process, and if any changes are required prior to sending it out to
ballot,
we will walk through those changes at the closing 802.3 plenary on
Thursday.

I realize that this is a very aggressive goal we are trying to attain,
but I
also have been extremely impressed by the volunteerism, dedication, and
detail that our team has applied to the problem. I hope that your review
of
this document confirms my impression.

Please jump over to our website at
http://www.ieee802.org/3/10GBCX4/index.html to see our progress and the 
working paper.

Best Regards,
