The only thing in the CMTS setup 900mbit that appears to be close to cake
is rate limiting with netem and applying codel
 as sub-qdisc.

host=mbox
tc qdisc replace dev ${host}.l root handle 1:0 netem rate 890mbit
tc qdisc replace dev ${host}.r root handle 1:0 netem rate 890mbit
tc qdisc replace dev ${host}.l parent 1:1 handle 10:1 codel
tc qdisc replace dev ${host}.r parent 1:1 handle 10:1 codel
