Re: [802.3_NGECDC] 10Mb/s Single Pair Ethernet ad hoc materials are online



Sorry I couldn't make the first call. 

I agree with the conclusion in the minutes on David Brandt's presentation on Reduced Minimum Frame Size but I notice an inaccuracy in one of the comments recorded in the minutes; i.e.,
"It’s beyond the scope of a PHY project, impacts 802.3 MAC, and also impacts 802.1. " 

"also impacts 802.1" isn't accurate. IEEE 802.1 standards such as IEEE Std 802.1Q have to work with a variety of IEEE 802 MACs and some, e.g. IEEE 802.11, don't have padding to achieve a minimum frame size. That was true of 802.4 and 802.5 as well so there never has been a higher layer assumption of a minimum frame size. Reducing minimum frame size shouldn't affect the assumptions of 802.1 standards. (Of course, even though it doesn't affect the standards directly, it could affect implementations of those standards as they may have architectural assumptions based on knowing that Ethernet has a minimum frame size.)

Regards,
Pat

The 10Mb/s Single Pair Ethernet study group web page is now online at http://www.ieee802.org/3/10SPE/index.html and  materials presented at Monday’s ad hoc have been uploaded

.

As a reminder, the next ad hoc meeting will be on Wednesday, August 31 at 7AM pacific time.  If you would like to request a presentation, please email Peter Jones (our ad hoc chair) and myself with the title, the presenter and an expected amount of time by end-of-day Friday August 26.

Draft presentations for posting are requested by 7am (pacific) Tuesday August 30.

 

As previously announced, until the first study group meeting at the IEEE 802.3 September interim, announcements will also be sent to the NGECDC reflector; however, PLEASE sign up for the 10SPE reflector, as this practice will discontinue soon.
