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?
servers --- delay --- isp --- mbox --- clients
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
tc qdisc replace dev isp.l root bfifo limit 1024k
tc qdisc replace dev isp.r root bfifo limit 1024k
tc qdisc replace dev mbox.l root cake bandwidth YYYmbit
tc qdisc replace dev mbox.r root cake bandwidth YYYmbit
