Kevin (et. al.),
Its interesting that Hugh is considering ACK/NACK at
the
MAC interface level.
One might speculate that is also appropriate at
the
PHY-to-PHY level, rather than PAUSE. It then
gives
the sender the options of sending other
frames
(possibly even of the same priority), rather
than
blocking when only one switch output queue
becomes
full.
That's closer to the bus backplane model, and
only
really useful within the backplane
environment
(or possibly computer room, as long as the
cable
is only a few frames long).
Probably works OK in that environment,
though.

All,
The materials
for the 802.3ar Congestion Management Task Force May interim meeting have
been uploaded. The URL is included below for
convenience:
You will find
that Hugh Barrass has submitted two presentations. In addition, three
presentations are included from last week's IEEE 802.1 interim meeting in
Berlin. Hugh has been given permission by the respective author's to
present/review/highlight during our meeting in Austin.
As chair, I will
structure the meeting so we spend the majority of time trying to satisfy the
TF objectives we've established and have committed to 802.3 WG we'd deliver
on.
Hope to see you
in Austin.
Kevin
