Each class has a qdisc attached.  By default, this is a FIFO one (First I=
n,=20
First Out).  You can replace it with a SFQ qdisc.  A SFQ qdisc will treat=
h=20
each flow with the same priority.  So one flow can not eat all bandwidth.

Can't find that page.

I think you can shape a lot of traffic with this setup, but I don't know=20
exactly.
