Hi all, Thank you for the clarification. We will try implementing a similar test. Thanks to the Cake community's continued support we were able to successfully merge the set-associative flow hash module into ns-3 ( https://gitlab.com/nsnam/ns-3-dev/-/merge_requests/209). Hopefully, we are able to achieve a similar result with the ack filter module and we will continue to work to do so.
