[LARTC] Some questions about hfsc

[Joshua Snyder]

I have been looking at the hfsc for some time as a replacement or at a
class that can be used like htb.  But I seem to have run into a problem.
With htb classes it is easy to make three or more levels of priority for a
connection.  All you need to do is to make classes and give them different
prio levels.  But it seems like you can only define a real-time bandwidth
and a link sharing bandwidth.  This seems like only 2 levels of priority.
Did I miss something?

If you want hierarchic structure you can try putting sub-qdiscs in
classes you want to have lower priority. The 'rt' service curves in that
qdiscs' classes would dequeue not to root class  but to classes they are
attached to.

I wonder what are the disadventages of such solution.
