cake vs sfq and fq_codel looks great! You already have fq_codel in the graphs, do you mean codel?

In terms of simulating CMTS I am trying to simulate a cable connection.
Is the following reasonable?
===========8<===========
servers --- delay --- isp --- mbox --- clients

delay:
tc qdisc replace dev delay.r root netem delay ZZms rate XXXmbit limit 100000
tc qdisc replace dev delay.l root netem delay ZZms rate XXXmbit limit 100000

isp:
tc qdisc replace dev isp.l root bfifo limit 1024k
tc qdisc replace dev isp.r root bfifo limit 1024k

mbox:
tc qdisc replace dev mbox.l root cake bandwidth YYYmbit
tc qdisc replace dev mbox.r root cake bandwidth YYYmbit
===========8<===========

That's really hard to argue with. An fq_codel same conditions (and
pfifo and pie) might be interesting here.
