That also depends on the setup of the other classes.  Can you give us more 
information like htb or cbq?  What do you want to do?  What have you tried so 
far?

You always needs a minimum burst and cburst.  If you use htb and if you don't 
specify it on the command line, htb will calculate it for you.

Htb tree:
                      20:1
       20:10                 20:11
20:200  20:201     20:210  20:211
http stream ensure 4Mbps
ftp stream ensure 2Mbps
smtp stream ensure 2MMbps
other stream ensure 2Mbps
so I want ensure 20:200 have 4Mbps for http
20:201 have 2Mbps for ftp and 20:210 have 2Mbps for smtp 
20:211 have 2Mbps for other stream(default class )
Each class don't permit lended or borrowed bandwith from each other.
This is I want to get.

Can you try to explain it a bit more?  

You created 4 classes, (200, 201, 210, 211) so I suppose you want :
200 : http traffic, 4Mbps
201 : ftp traffic, 2Mbps
210 : smtp traffic, 2Mbps
211 : other trafic, 2Mbps

Each class is isolated so it never lends it unused bandwidth to other classes.  
And each class is never using unused bandwidth from other classes. So as 
example, http has 4Mbps and it never can use the bandwidth of ftp (2Mbps) if 
there is no ftp traffic.  So the 4Mbps is a maximum bandwidth.

What's the total bandiwidth available?  You have 4Mbps for http and 3x2Mbps 
for ftp,smtp,other.  So the total bandwidth available on the link is 10Mbps?

No problem.

I have some remarks.  Why not let the 4 classes borrow unused bandwidth from 
each other?  So if there is no other traffic then ftp, ftp can get 10Mbps.  
But as soone as there is some other traffic, the ftp traffic goes down.

And if you want 4 isolated classes, why not just creating the 4 classes like 
this :

                   20:1
20:200  20:201 20:210  20:211

You have to create the htb (or cbq) classes.  FIltering the traffic and 
placing in the classes is easy (you can filter on ports).  Except maybe for 
the ftp traffic because that uses dynamic ports.

Stef:
Thanks for your answer me quickly!
I have others question :)
I apologize that it will take time.
My topological look like this:
Local:192.168.1.2----------|eth0:192.168.1.1 Linux Box eth1:172.16.1.1|------Internet

I have create a default 200

             20:1 (4kbps)
200:200 200:201 200:210 200:211
(1kbps) (1kbps) (1kbps) (1kbps)

I have 10Mbps on the eth1,but I want to test htb,so I do that:
tc class add dev eth0 parent 20: classid 20:1 htb rate 4kbps ceil 4kbps
 

200:201 mark with 7,then 
iptables -t mangle -A FORWARD -p tcp -o eth0 -s 0/0 --dport 80 -d 0/0 -j MARK --set-mark 7
iptables -t mangle -A PREROUTING -p tcp -i eth0 -s 0/0 --dport 80 -d 0/0 -j MARK --set-mark 7

why all traffic from default 200 to Internet.(the iptables rules like no use)


------------------------------------------------

If I use it on eth1 interface iptables rules work!?(though I have default class 200 but all traffice 
from 200:201 to Internet.) other question it that:
In this settings use Local machine 192.168.1.2 download some soft from Internet.why it rate overrun 1kbps?
 
Rules like this:
tc class add dev eth1 parent 20: classid 20:1 htb rate 4kbps ceil 4kbps

iptables -t mangle -A FORWARD -p tcp -o eth1 -s 0/0 --dport 80 -d 0/0 -j MARK --set-mark 7
iptables -t mangle -A PREROUTING -p tcp -i eth1 -s 0/0 --dport 80 -d 0/0 -j MARK --set-mark 7

tc can only shape outgoing traffic(My settings which is my outgoing traffic,eth1 or eth0?) Maybe I mix them
I need path kernel with IMQ?

I have some problems understanding your english.  Can you post your htb and 
iptabels script so I can understand what you did?

4 and 1 kbps is __very__ low.  It's too low for htb to get some results.

So all traffic ends up in 200:200 ??
You can check with iptables -L -v -n if your iptables rules are matched.  If 
the iptables rule match, the byte and packet counters will increase.

Because 1kbps is too low for htb.  And you have to mark packets in 
POSTROUTING.  Local generated packets don't travel thru forward or 
prerouting.  See kptd on www.docum.org.

You can indeed only shape outgoing traffic.  Or you need the imq device.  But 
if you shape on eth0 and eth1 you control both directions.  So you don't need 
the imq device.

when I use iptable -L -v -n -t mangle,I have below infor
PREROUTING chain:
 pkts bytes target     prot opt in     out     source               destination
 305 40889  MARK       tcp  --  eth0   *       0.0.0.0/0            0.0.0.0/0          tcp dpt:80 MARK set 0x3

why not stream through ForWard chain ? beacause this all traffic into 20:20(default class)?

Your script seems ok to me.

So the packets get marked.

I suppose you execute
tc -s -d class show dev eth0
to see the counters increase for the 20:20 class and not for the other class?  
If you didn't execute that command before, can you do so and check the 
counters for the different classes?

Re: [LARTC] How to do ensure bandwith

hi:
Stef and everybody
I use tc with htb more than one month.
This is my Network settings 
Local Network 192.168.1.0/24 ---| eth0:192.168.1.1 Linux Box eth1:172.16.1.1 | -- Internet 
In order to ensure bandwidth
on eth1 I have create a default 20 
              20:1 (10Mbps)
 20:20 20:21 20:22 20:23 20:24
(20Mbps) (20Mbps) (20Mbps) (20Mbps) (20Mbps) 
on eth0 I have create only a default 20
    30:1 (10Mbps)
 30:20
(10Mbps) 
Each class is isolated so it never lends it unused bandwidth to other classes.  
And each class is never using unused bandwidth from other classes. 
first,eth1 and eth0 with same bandwith,I use eth1 Interface ensure totoal bandwith with 10Mbps. then I part eth1 with fine 
qdisc.
My script that: 
tc qdisc add dev eth0 root handle 20: htb default 20
tc class add dev eth0 parent 20: classid 20:1 htb rate 10240kbps ceil 10240kbps
tc class add dev eth0 parent 20:1 classid 20:20 htb rate 10240kbps ceil 10240kbps
tc qdisc add dev eth0 parent 20:20 sfq 
tc qdisc del dev eth1 root
tc qdisc add dev eth1 root handle 30: htb default 20
tc class add dev eth1 parent 30: classid 30:1 htb rate 10240kbps ceil 10240kbps
tc class add dev eth1 parent 30:1 classid 30:20 htb rate 2048kbps ceil 2048kbps
tc qdisc add dev eth1 parent 30:20 sfq
tc class add dev eth1 parent 30:1 classid 30:21 htb rate 2048kbps ceil 2048kbps
tc qdisc add dev eth1 parent 30:21 sfq
tc class add dev eth1 parent 30:1 classid 30:22 htb rate 2048kbps ceil 2048kbps
tc qdisc add dev eth1 parent 30:22 sfq
tc class add dev eth1 parent 30:1 classid 30:23 htb rate 2048kbps ceil 2048kbps
tc qdisc add dev eth1 parent 30:23 sfq
tc class add dev eth1 parent 30:1 classid 30:24 htb rate 2048kbps ceil 2048kbps
tc qdisc add dev eth1 parent 30:24 sfq
tc filter add dev eth1 parent 30: protocol ip  handle 1 fw classid  30:20
tc filter add dev eth1 parent 30: protocol ip  handle 2 fw classid  30:21
tc filter add dev eth1 parent 30: protocol ip  handle 3 fw classid  30:22
tc filter add dev eth1 parent 30: protocol ip  handle 4 fw classid  30:23
tc filter add dev eth1 parent 30: protocol ip  handle 5 fw classid  30:24  

iptables -t mangle -A FORWARD -p tcp -o eth1 -s 192.168.1.2/32 --dport 80 -d 202.197.240.6/32 -j MARK --set-mark 3
iptables -t mangle -A PREROUTING -p tcp -i eth1 -s 192.168.1.2/32 --dport 80 -d 202.197.240.6/32 -j MARK --set-mark 3
iptables -t mangle -A FORWARD -p tcp -o eth1 -s 192.168.1.2/32 --dport 80 -d 195.27.176.155/32 -j MARK --set-mark 4
iptables -t mangle -A PREROUTING -p tcp -i eth1 -s 192.168.1.2/32 --dport 80 -d 195.27.176.155/32 -j MARK --set-mark 4
iptables -t mangle -A FORWARD -p tcp -o eth1 -s 192.168.1.2/32 --dport 80 -d 218.104.154.19/32 -j MARK --set-mark 5
iptables -t mangle -A PREROUTING -p tcp -i eth1 -s 192.168.1.2/32 --dport 80 -d 218.104.154.19/32 -j MARK --set-mark 5 

I think that all traffic must thro eth0,then it will thro eth1 of one qdisc. 
If my script is right ,I hope it will help newbie of tc.
If it mistake ,please everyone tell me :)
