HTB Rate and Prio
Hi,
I wanted to implement some QOS on my Linux Box with HTB, but after some time
spend
on the configuration and tests, I still don''t manage to have some correct
results. Here are the details :
-ROOT 2000 kbits
-HIGHPRIO SUBCLASS 50 kbits prio 0
-SUBCLASS1 750 kbits prio 1
-SERVICE1 250 kbits prio 1

I just tried to change {,c}burst to 1600, or leaving them by default but
no visible result.

htb and fw problems
Dear All,
I''m using the kernel 2.6.6, iproute2-2.4.7.20020116, iptables v1.2.9, and gentoo.
I have a leased-line 64 kbps.
I can see the counter works in iptables, but in the htb, it doesn''t go to the right class (it always go to the default class).
Any help will be appreciated
here''s my htb conf
#!/bin/bash
tc qdisc del dev eth1 root
tc qdisc add dev eth1 root

Howto Graph throughput?
I have successfully implemented a QoS system using HTB on a 2Mb/s
leased line and it works very well, but I would like to be able to
graph the three pipes to see what they are doing, eg: using MRTG or
similar.
Has anyone any experience or examples of how to do this please?
Thanks,
Chris

Where is the documentation for IFB ?
Hi all,
Can you tell me where is the documentation for the new IFB (implemented
in kernels > 2.6.16).
Thanks in advance!

how to do probabilistic packet loss in kernel?
Hi,
I am using iproute2 to setup fowarding, adding routes like "ip route add 192.168.1.3 via 192.168.1.2"
I was wondering where in the kernel I can insert probabilistic packet loss only for forwarded packets? So that for instance I can drop 5% of all forwarded packets?
I don''t need help with the actual code, just need help finding where to insert this code :)
Thanks!

ctokens vs tokens - HTB.
Hi,
One more of those ...
1) what is a ctoken with regard to HTB? Does the ''c''
stand for ceil and if so how is it different from
tokens?
2) Is the difference, only in the generation of these
tokens?
3) Would the ctokens and token be treated equally once
borrowed?
Kindly help.
Thank you.
Regards,
suraj.

htb2 -> htb3 problems
Hello!
I need to switch from htb2 to htb3, because of speed issues (for me,
htb2 is unable to handle more then 100mbit duplex with ~550 classes),
kernel profiling shows htb_dequeue_prio at 1st place with 3x isolation.
So, I''ve moved from 2.4.19 to 2.4.25 kernel (hi-pac for classification/marking
and htb3 for queueing), and traffic rate drop from 100 to 20mbit.
What can be wrong? The

TC (HTB) doesn''t work well when network is congested?
Hi,
I have a server and ten clients in a Gigabit network. The server has
125mbps network bandwidth.
I want that the server has 40Mbps bandwidth reserved for client 1 (IP
192.168.5.141), and the
rest bandwidth is for all other clients.
My script looks like this (I use IFB for incoming traffic):

HTB has 2 bucket?
in HTB use 2 bucket for manage 2 rate???
first bucket -> keep token for sending with rate
second bucket -> keep ctoken for sending with ceil rate
Is it true?? may be i''m misunderstand about token/bucket thoery

I''ve attached the output from the command you requested below.
I''m using kernel 2.6.17.12 and tc version ss060323. I''m have a nforce4

difference.
Charlie,
I''ll take a look at the Apache model for throttling, thanks. I was going

tbf initial burst
I am using tbf to do bandwidth limitation. i found that when i start passing traffic there is a burst and then the rate goes down to what is configured. is this a known issue or do i need to change some parameters?
thanks.

QOS monitoring?
Hi,
I have implemented QOS classifiers using TC with HTB. The
classification is working.
I would like to know whether there is some tool which will help me in
monitoring the bandwidth share of the various classes.
Thanks,
