Well, fq_codel 'sparse flow' is not going to state that a flow sending one packet every 100 ms is a 'good guy' meaning it needs a boost. This kind of flow (paced but sending 10 packets per second) will use the normal RR mechanism. However, he will get a normal share, compared to some elephant flows. fq_codel 'boost' is only for first packets of a new flow. _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
