Re: [RE] Stream identification at the MAC SAP
I don't think that when you are potentially running several 20MB/s HD video
streams over your network and then someone wants to copy a DVD sized file
from one computer to another that over-provisioning is going to be up to the
task. You can always find a way to saturate the network. I believe that we
need both QoS and reservation.

I believe that adequate QoS on a home scale network can be achieved easily
with layer 2 protocols and over-provisioning.
My arguments on this topic were not well received here.

Seems like people have already tossed the PBX out the window, and they're
not having any problems. So if that the benefit of RE, its a little late.
And all of those real-time and synchronized applications working great, and
outside the scope of 802. Which is (not coincidentally) one of my big
questions about some of the work being investigated by this study group -
why does 802 need to define isochronous services at all?
People have been running real-time and synchronized applications over
Ethernet for a long time. Timing issues are generally best addressed
end-to-end at the application layer, and above L2. Not everything has to be
addressed within 802.3.
