I'm trying to set up a traffic control on ingress attaching a egress qdisc to the ifb device. The idea is to use a RED algorithm instead of policing the incoming traffic. After trying with tc-red and not obtaining the expected results, I decided to try with something easier, and use htb as bottleneck: ifconfig ifb0 up tc qdisc del dev $dev ingress tc qdisc del dev ifb0 root tc qdisc add dev $dev ingress tc filter add dev $dev parent ffff: protocol ip prio 10 u32 \ match u32 0 0 flowid 1:\ action mirred egress redirect dev ifb0 (1) tc qdisc add dev ifb0 root handle 1: htb default 1 (2) tc class add dev ifb0 parent 1: classid 1:1 htb burst 0 rate 112kbit Now I generate some traffic: $ scp user@host1:~/reallylargefile . reallylargefile 0% 64KB 12.4KB/s 7:52:29 and I get the expected results, if instead of htb I use something like RED, changing lines (1) and (2) with tc qdisc add dev ifb0 root handle 1: red limit 256000 min 1 max 32000 avpkt 1 burst 1 probability 0.8 bandwidth 512 I don's see any dropped packets at all. (I know that the values of min, avpkt and burst are extremely low, and that probability is extremely high, but I just tweakeed them hopping to see dropped packets) Did I completely misunderstod the how red works? Thank you. _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
