Re: [802.3_OMEGA] Comments on P802.3cz project documents



Ruben:

The balanced costs item in the CSD was created when 802 projects almost always addressed enterprise networks.  The end stations were workstations/desktop computers and servers, and infrastructure included the enterprise cable plant, routers and bridges (switches), wireless access points, etc.  That holds together roughly for newer applications.  

IMHO, telecommunications applications break down as I personally consider all of the metropolitian and wide area links and associated equipment as infrastructure.  For most of that application, none of the traditional division holds.  Few “end stations” connect directly to the metropolitan or wide area network. 

Automotive is somewhat different as we know.  The cabling, end stations and bridges in an auto network are all engineered.  I equate an ECU to a server, but that ECU may have bridge functionality built into it so it can have what has traditionally been end station and infrastructure functionality.

Both the Responses and Motions files for 15 May contain my cut at a response to the 802.1 question.  George Zimmerman is handling it for B10GAUTO folk this week, and has asked for more clarification from 802.1 on what they really want (as opposed to my thinking what I thought they meant).  We will want to make the responses the same for P802.3cy and P802.3cz as both received the same comment on identical CSD text.

Bob,

I would like to know what is meant in other projects with "The balance of costs between infrastructure and attached stations is not applicable to the automotive environment.”. What is infrastructure and what is station and what is the rational behind this requirement. Understanding well these points
are the basis to build an answer to the comment.

Thanks

Colleagues:

As mentioned on our 12 March teleconference, we have received PAR and CSD comments from 802.11.  See slide 13 of mentor document 11-20/264r3:
https://mentor.ieee.org/802.11/dcn/20/11-20-0264-03-0PAR-par-review-sc-meeting-agenda-and-comment-slides-march-2020-atlanta.pptx.

We just received comments from 802.1.  P802.3cz and P802.3cy have the same CSD-Economic Feasibility response and received the same comment.  The comment document is:  http://www.ieee802.org/1/files/public/docs2020/admin-PAR-CSD-comments-802-3-0520-v02.pdf and the two comments are slides 3 and 4.  

The 802.11 comments will not require changes to our PAR or CSD.  If you have any suggestions for a response on the 802.1 comment, I’m open to hearing it, and will work with the B10GAUTO leaders to draft a common response.
