Hello, I am using a simple script, which is based on prio. The point is, that it is not possible to use htb on wifi networks, so I thought that prio will work fine, but it does almost nothing.
All I wanted was to make the important packets like icmp, games, VoIP,... to go first, and to slow the things like FTP data transfer, etc.
When I use $TC -s qdisc show dev ${IFACE}, I see, that the packets go to correct qdiscs. But when I start FTP data transfer, then the ping time is same with and without this shaping.
I should also mention, that I am testing it on WiFi with hostap drivers, where the ping times are about 2-3ms when idle and 100-150ms durring high traffic.
Is the first/fastest prio class really 1:1, and the last/slowest is 1:4?
Or did I miss something else?
A part of the code follows:
$TC qdisc add dev ${IFACE} root handle 1:0 prio bands 4 priomap 2 2 2 2 2 2 0 0 1 2 2 2 2 2 2 2 2>/dev/null
$TC qdisc add dev ${IFACE} parent 1:1 handle 10 sfq quantum 1514b perturb 10 $TC qdisc add dev ${IFACE} parent 1:2 handle 20 sfq quantum 1514b perturb 10 $TC qdisc add dev ${IFACE} parent 1:3 handle 30 sfq quantum 1514b perturb 10 $TC qdisc add dev ${IFACE} parent 1:4 handle 40 sfq quantum 1514b perturb 10
$TC filter add dev ${IFACE} parent 1:0 protocol ip handle 1 fw flowid 1:1 $TC filter add dev ${IFACE} parent 1:0 protocol ip handle 2 fw flowid 1:2 $TC filter add dev ${IFACE} parent 1:0 protocol ip handle 3 fw flowid 1:3 $TC filter add dev ${IFACE} parent 1:0 protocol ip handle 4 fw flowid 1:4
$IPT -t mangle -A POSTROUTING -o ${IFACE} -j MARK --set-mark 1 ....... $IPT -t mangle -A POSTROUTING -o ${IFACE} -p tcp --dport 20 -j MARK --set-mark 2 $IPT -t mangle -A POSTROUTING -o ${IFACE} -p tcp --sport 20 -j MARK --set-mark 2 .......
You need to limit the rate to less than link speed by making the prio a child of an htb class.
Andy.
