How does that idea sound to you? That will result in a cliff-edge policer (i.e., as soon as a device goes over its limits it will see every packet get dropped). This doesn't interact too well with the burstiness of TCP, so you'll likely get erratic behaviour of the traffic if you do that. Doing the same thing with HTB means the router will queue+shape each class (and with FQ-CoDel on the leaves, you'll get a nice AQM behaviour as well), so that will be smoother and less prone to bloat :) -Toke
