Re: [802.3EEESG] P802.3az approved! (and call for presentations)

[Mike Bennett <mjbennett@xxxxxxx>]

Folks,

I would like to point out that there were two presentations for the Seoul, Korea meeting that were submitted prior to the deadline and I neglected to summarize those in the previous e-mail.  I meant no disrespect to those who submitted and presented those materials and I consider them to be valuable contributions to our work - just as the ones submitted at the meeting were valuable.

The first presentation was an analysis of cost and power for the subset PHY.  Wael Diab reviewed some of the power savings numbers discussed in previous study group meetings, provided some of the details behind the numbers and attempted to connect the numbers to the proposal using 10GBASE-T as a reference.  He presented a spreadsheet comparing 10GBASE-T and subset PHY power drivers, as well as the assumptions used for the comparison.

The next presentation was a look at the applicability of EEE to fiber PHYs.  Brian Holden presented on behalf of Onn Haran.  He gave some background regarding speed changes not being feasible for optical components, suggested a mechanism similar to what has been called "0BASE-T" is feasible and desirable for fiber PHYs and listed a set pf PHYs for which it should be considered.  There was a reference to target markets, and a high level explanation of how  mechanism would work to achieve energy-efficient optical PHYs.

The presentations and details regarding the discussions on them (located in the unapproved meeting minutes) are on the web site.

Best regards,

Mike

Colleagues,

P802.3az approved!

NesCom recommended approval of  P802.3az yesterday and the Standards Board approved it this morning.  I congratulate you and thank the members of the study group who contributed their time and effort to make this happen.

EEESG update

The meeting in Seoul, South Korea went well.  The unapproved minutes for July and September are on the web site, as well as a spreadsheet we can use to help make technology decisions in task force.  The spreadsheet is in draft form and will be updated as we make progress.  If you are planning to present in November, you should have a look at it to see the items we will consider for comparison and use this as a reference for developing your presentation.

We had two presentations submitted at the Seoul meeting.  David Law analyzed the impact of frame loss in a protocol-based speed change and Bob Grow reported feedback from 802.1 based on a brief presentation he gave at their meeting during the week of September 3^rd.   David asked whether or not we should be considering alternatives to frame-based protocols for speed changes.  I think we need to do so.   The study group agreed that I should give a short presentation at the opening 802.1 plenary meeting during the liaison reports to inform their working group of our work and invite people to attend our meetings and contribute.  It is very important that we work together to minimize impact on time-critical protocols such as those being developed for AVB. 

Call for presentations

The first meeting of the 802.3az task force will be held during the week of November 11-16 at the Hyatt Regency Atlanta in Atlanta Georgia.  See http://www.ieee802.org/meeting/index.html for meeting and registration information.  I would like us to hit the ground running at our first task force meeting.  Presentations should be focused on proposals as we work towards developing a baseline.  My goal is to adopt the baseline set of proposals at the end of the March 2008 meeting.  I believe this is achievable if we get off to a good start at this meeting.

Prospective presenters may submit your request per the guidelines at the Procedure for Presenters web page:

http://grouper.ieee.org/groups/802/3/eee_study/public/presentproc.html

Presentation requests and materials are due to me by Wednesday, November 7th.  Presentations should be mailed to me at mjbennett@ieee.org.   Early requests and / or submissions are appreciated.  Please remember that any requests for time or submissions of presentation material containing restrictive notices will be rejected.

Best regards,

Mike
