Yes, we did realize that rte_sched is not suitable for AQM algorithms.
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. It is latest and most complete
and the developers are active and friendly.

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.

Hello everyone,

We have been using DPDK's QoS framework over the last year and found
that rte_sched and the provided qos_sched app work great for QoS.

However, when we ventured into trying to add CoDel (to replace RED) as
a dropper to the framework, we faced several challenges due to how
tightly rte_sched and rte_red were coupled together. As we had no
success with rte_sched, we would like to propose a new framework for
queue management in DPDK.

Goals we have in mind for the framework:
- Act as an abstraction for queue management algorithms (AQMs) such as
CoDel, PiE and RED.
- Make it easy for new algorithms to be added.

We’d appreciate feedback on whether such a framework would be welcomed
in the community, or what else could be done for adding queue
management support.

Sincerely,
Archit Pandey.
