Well im currently using:
#root device
$TC qdisc add dev $INTERFACE root handle 1: htb default 25
#root class
$TC class add dev $INTERFACE parent 1: classid 1:1 htb rate 256kbit
#20 - ICMP, DNS, SYN, SSH
$TC class add dev $INTERFACE parent 1:1 classid 1:20 htb rate 128kbit ceil 256kbit prio 1
$TC qdisc add dev $INTERFACE parent 1:20 handle 20: sfq perturb 10
$TC filter add dev $INTERFACE parent 1:0 prio 0 protocol ip handle 20 fw flowid 1:20
#21 - HTTP/FTP out
$TC class add dev $INTERFACE parent 1:1 classid 1:21 htb rate 128kbit ceil 256kbit prio 2
$TC qdisc add dev $INTERFACE parent 1:21 handle 21: sfq perturb 10
$TC filter add dev $INTERFACE parent 1:0 prio 0 protocol ip handle 21 fw flowid 1:21
#22 - All cool.comp traffic
$TC class add dev $INTERFACE parent 1:1 classid 1:22 htb rate 128kbit ceil 256kbit prio 3
$TC qdisc add dev $INTERFACE parent 1:22 handle 22: sfq perturb 10
$TC filter add dev $INTERFACE parent 1:0 prio 0 protocol ip handle 22 fw flowid 1:22
#23 - All ian.comp traffic
$TC class add dev $INTERFACE parent 1:1 classid 1:23 htb rate 64kbit ceil 256kbit prio 4
$TC qdisc add dev $INTERFACE parent 1:23 handle 23: sfq perturb 10
$TC filter add dev $INTERFACE parent 1:0 prio 0 protocol ip handle 23 fw flowid 1:23
#24 - HTTP/FTP in
$TC class add dev $INTERFACE parent 1:1 classid 1:24 htb rate 64kbit ceil 256kbit prio 5
$TC qdisc add dev $INTERFACE parent 1:24 handle 24: sfq perturb 10
$TC filter add dev $INTERFACE parent 1:0 prio 0 protocol ip handle 24 fw flowid 1:24
#25 - Everything else
$TC class add dev $INTERFACE parent 1:1 classid 1:25 htb rate 20kbit ceil 64kbit prio 8
$TC qdisc add dev $INTERFACE parent 1:25 handle 25: sfq perturb 10
$TC filter add dev $INTERFACE parent 1:0 prio 0 protocol ip handle 25 fw flowid 1:25
Ill do some more tests and link to a rates graph when done.
It should illustrate the problem.
Thanks again,
Mark.
