But what has this to do with traffic shaping You can mangle incoming and outgoing packets with iptables, but tc kicks in just before the packets are placed on the wire. So after all iptables stuff and only for the outgoing packets.

And it's not because there is no queue for incoming packets that you can't do anything with time. The filter + policer setup can rate limit incoming packets. Iptables can also do rate limiting.

For now i am not applying IMQ for the ingress, but using packet mangling under iptables to handle both incoming packets from internet and outgoing packets to internet. Is this not right? give me your opinion please, as far as i can see, there were no troubles using packet mangling to handle those situation.

Htb is an egress qdisc so it shapes outgoing traffic. An ingress qdisc handles the incoming packets. And there is no queue for the incoming packets, so you can't use htb. You can use filteres + policers to rate limit traffic. Or you may take a look at the imq device. This is a virtual device. You can redirect all incoming packets to it and use htb on the imq device.

Oh ok, it's working now. The script is fine. My test tool isn't accurate. Now i have test with iperf and get accurate result. Other question ...:) which ingress qdisc that accurate like htb?

For details, check: http://bugme.osdl.org/show_bug.cgi?id=657 In short, it seems bandwidth limiting behaves strange for different outgoing packet sizes.

Just for the record, in the middle of some network performance test for some sort of appliance I capped outgoing speed to 25 Mbps on my PIII 600 MHz with a 3Com 100 Mbps card, and the box barely spends 1-2 % of CPU transmitting at "full" speed (full = 25 Mbps).

[LARTC] >10Mbit on HTB
Below is the script: tc qdisc del dev eth2 roottc qdisc add dev eth2 root handle 1 htb default 10 r2q 100 tc class add dev eth2 parent 1: classid 1:2 htb rate 100Mbit tc class add dev eth2 parent 1:2 classid 1:10 htb rate 20Mbit ceil 20Mbittc filter add dev eth2 parent 1:0 protocol ip prio 100 u32 match ip dst 202.xx.xxx.xx/26 classid 1:10 When i try to shape 20Mbit, there's dropped packet but i see the bandwidth not shaped to 20Mbit. But when shape to 10Mbit, i see the bandwidth down to 13Mbit. Any comment with this? Thanks.
[LARTC] >10Mbit on HTB
I want to try to shape 20-30Mbps traffic using HTB. It's possible? Anyone already try this? Thanks.
