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<=========== George On Fri, Dec 1, 2017 at 2:23 PM, Dave Taht <[email protected]> wrote: > That's really hard to argue with.
