Denis,

Why you are asking this?

In my mind the flow control is no more needed. At least the combination makes no sense for me from the standpoint of applications.

There was a similar discussion during the joint .1TSN and .3br meeting with the conclusion that flow control can be substituted by this better approach of IET combined with the different .1TSN approaches on top.

Ludwig,

Glancing through the latest P802.3br, there is no comment on the operation between IET (P802.3br) and flow control.

Is 802.3x link based flow control possible?

Is 802.3bd priority based flow control possible?

If either is possible, are they on the express MAC or preemptable MAC?

Regards

Dear IET colleagues,

This evening, the IEEE 802.3 approved unanimously, in its closing plenary, starting WG ballot on IEEE P802.3br, D2.0. Pat will produce D2.0 by removing the change tracking information and updating the first page.

The closing plenary report of IET rev 0 was changed according to the latest motion to add a needed sentence in the WG motion and during the closing plenary I was requested to change the D1.9 to D2.0 in the motion. This resulting closing plenary presentation of IET is on the server as rev1.

Please be prepared that I will announce in conjunction with Michael for 802.1 TSN that we will have a series of joint teleconference meetings to do initial comment resolution before the next interim in Pittsburgh using the day and time of the usual 802.1 TSN meetings.
