Doesn't work on ingress presently, if you are using ifb (I can be wrong). Using something to lightly shape the last hop (host) incoming packets, like htb set to a very large fraction of the card's bandwidth and codel set to a target of 500us delay on ingress, seems to work. With egress and ingress rate limiting on I can get delay for large numbers of flows in both directions in a saturated situation down to < 5ms with fq_codel in place attached to htb. Best of all, if you have ecn enabled on that host and the packets are marked 3 on ingress in that scenario, you don't drop anything on that last hop... > > -- Juliusz > -- Dave Täht SKYPE: davetaht US Tel: 1-239-829-5608 http://www.bufferbloat.net _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
