We have implemented a bare-bones AQM mechanism that is independent of rte_sched. Using this implementation we have successfully added and tested PIE and CoDel. > I would recommend starting with Cake.

CAKE can be added using what we have built, but before we do that we wanted to know if such a feature would be welcomed by the community. Subsequently, we will submit an RFC patch series to the dev mailing list. Thanks, Archit Pandey.
