Here is an addapt of my script but you'll have to compile htb into the
kernel and iproute2; see also

qdisc->class_limit_48---class 1   4  Kb -> qdisc sfq
                                       \_class 2   4 Kb -> qdisc sfq
                                       \_class 3   8 Kb -> qdisc sfq
                                        \_class 4  32 Kb -> qdisc sfq

... tc filter to put IP in classes. It should go like this:

tc qdisc add dev eth1 root handle 1: htb default 10

tc class add dev eth1 parent 1: classid 1:1 htb rate 48kbit ceil 48kbit
burst 1k

tc class add dev eth1 parent 1:1 classid 1:10 htb rate 4kbit ceil 48kbit
burst 1k
tc class add dev eth1 parent 1:1 classid 1:11 htb rate 4kbit ceil 48kbit
burst 1k
tc class add dev eth1 parent 1:1 classid 1:12 htb rate 8kbit ceil 48kbit
burst 1k
tc class add dev eth1 parent 1:1 classid 1:14 htb rate 32kbit ceil
48kbit burst 1k

tc qdisc add dev eth1 parent 1:10 handle 20: sfq perturb 10
tc qdisc add dev eth1 parent 1:11 handle 30: sfq perturb 10
tc qdisc add dev eth1 parent 1:12 handle 40: sfq perturb 10
tc qdisc add dev eth1 parent 1:14 handle 50: sfq perturb 10



tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst
192.168.0.11 flowid 1:10
tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst
192.168.0.22 flowid 1:11
tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst
192.168.0.33 flowid 1:12
tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst
192.168.0.44 flowid 1:13
