Hi all,

Thank you=C2=A0for the clarification.= We will try implementing a similar test.

Thanks t= o the Cake community's continued support we were able to successfully m= erge the set-associative flow hash module into ns-3 (https://gitlab.com/nsnam/ns-3-= dev/-/merge_requests/209).

Hopefully, we are a= ble to achieve a similar result with the ack filter module and we will cont= inue to work to do so.=C2=A0

Thanks,

The test was run on a complete implementation of Cake, set up in the normal= way.=C2=A0 I think we kept the configuration simple for this test, so ever= ything at defaults except for choosing the shaped bandwidth in each directi= on.

The ack-filter relies on having fairly good flow isolation, so that consecu= tive packets in the appropriate queue belong to the same ack stream.=C2=A0 = So at minimum it is appropriate to have the set-associative flow hash enabl= ed.

The host-fairness and Diffserv features were probably enabled, but did not = have relevant effects in this case, since only one pair of hosts and the Be= st Effort DSCP were used in the traffic.
