[802.3AZ] project update
Folks,
The March plenary meeting went well. We managed to close most of the
TBDs, account for the wake shrinkage times for all PHYs except
backplane, and include the transmit and receive state diagrams for L2 in
clause 78. We also adopted a containment model for L2 at a joint
meeting with the 802.3at and maintenance task forces. Nonetheless, we
still have work to do to meet the goal of having a draft that is
technically complete.
There are architectural inconsistencies we need to resolve. We need the
wake time shrinkage values for the backplane PHYs and we need to make
sure Low Power Idle (LPI) does not have a negative impact on link fault
signaling. We also need to incorporate the changes required for the
containment model.
The Wake Time Shrinkage Ad-Hoc will continue to work on the calculations
for the backplane PHYs and provide us with recommendations and minimum
values, if needed. The L2 Ad-Hoc will continue to work on the
containment model and refinement of the L2 section of clause 78. I have
also chartered an Ad-Hoc to determine whether or not LPI has a negative
impact on link fault signaling. George Zimmerman is chair of that
Ad-Hoc. If any of you are interested in contributing to that effort,
please contact him. George will send meeting information to the
reflector soon.
Our plan is to post Draft 1.3 on March 30. We need to scrutinize
version 1.3 to make sure there are no holes, that the remaining TBDs,
which are mainly cross references, get filled in, and that the
architecture is consistent. If we post D1.3 on time, our comment
deadline will be April 17. Please plan time to review the draft
carefully as we do not want to have to make a lot of changes to the
draft we offer for preview, D1.4, by the Working Group after the May
meeting.
I would like to thank Sanjay and our editors for their continued hard
work, as well as our Ad-Hoc chairs David Law and Wael Diab, and Ad-Hoc
participants for bringing in the contributions that allowed us to close
so many of the open items we had. Also thanks to the Task Force for
making last week's meeting so successful.
Lastly, Final comment responses on Draft 1.2.1 have been posted as well
as the March meeting minutes.
Best regards,
Mike
