Well, you need to understand what's happening to the packets end-to-end -
that's not necessarily the same thing as altering the PHB on each and every
device end-to-end.

Classification, LLQ / CBWFQ, etc at the edge, and constant surplus bandwidth
with negligable serialization delays in the core can work perfectly well, as
long as you can control the core and be very sure that's what you have.

Regards,
Tim.
