If you have several MAC-layer queues, then do you have
another set of MAC-layer scheduling? If so, how do you
select the algorithm?
I suggest this can of worms requires further thought
before we end up with two layers of QoS queuing and
scheduling.
Cheers,
Glen
PS: Can we *please* deprecate use of the ToS bits. We had
almost killed them and Linux is again encouraging their
use, much to the despair of network operators (who want
DiffServ, or at least DiffServ-compatible use of IP
Precedence)
