Hi Colton,
I'm pretty sure Juniper don't have anything like fq-codel in any of their
products however, the place to do that would be on the CPE or edge access
switch/router not your core.
Normally one would rate limit the customer on CPE LAN ingress and egress if
you're doing multi-colour policing, or CPE WAN ingress and egress if just hard
policing, or CPE WAN egress and PE egress if doing shaping. You don't want your
customer to blast traffic into your network and this have to carry those
packets across your core only to them drop them on your expensive subscriber
management box.
One normally wants to drop excess packets as close to the source as possiblr.
So for that reason you want fq-codel on your CPE.
Cheers,
James.
