[802.3_ISAAC] Discussion on comment #13

All,

 

I took an action to provide a response to reject.

 

Propose Reject

Annex 191A is informative because this is difficult to practically measure on a single PHY.  Otherwise, this would have been made normative. 

 

However, in a system where there are 2 PHYs (same or different vendors it does not matter) the system path delay becomes measurable and the total delay is normative and is required to support Pause.

 

Annex 191A is there in the spirit that vendors will voluntary meet this so that the system integrator can meet the normative spec.  It also eliminates uncertainty for PHY vendors on how much delay to target. If a vendor meets the target voluntarily, they would know they will be compliant in a system when working with another vendor who meets the number voluntarily.

 

 

Thanks,

William
