[c-nsp] QoS Question

[Rodney Dunn]

CBWFQ doesn't really depend on the L2 encapsulation.

I think what you were aiming at was the fact that
QOS doesn't kick in without congestion.

In a frame-relay environment you may not have a
way to detect congestion so you do shaping with
queueing on top of it.

With straight point to point T1's the driver code
detects congestion and backs packets up in the queues
so the QOS can be done on them.
