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=E2=80=99d appreciate feedback on whether such a framework would be welco= med in the community, or what else could be done for adding queue management support. Sincerely, Archit Pandey.
