Certainly it is a classful queueing discipline. Just to sync with you, what do
you mean with per-flow as opposed to class-based?
Do you mean that the scheduler internally and autonomously differentiates
packets into distinct flows according to some internal classification rule (as
it is the case for SFQ)?
If so, then you are right.
Class-based queuing and flow-based queuing of course are different things,
but from your demo I got the impressions that you were using class and flow
interchangeably.
In practice, I do not see when you would need 500 classes while it might
happen
to have 500 flows (active and in progress ) on a link.
I think both are needed but while class-based queuing is well accepted
flow-based is not.
