Greetings,

Scenario:
Centos box with eth1 (10.0.0.0/24) and eth0 (192.168.0.0/24)
segment on eth0 has access to full bandwidth of uplink

Both are on 100mbps switches

Requirements:
bandwith on segment on eth1 needs to be throttled to different speeds - say 32, 64, 128kbps and the such. Required for application performance testing purposes.


As usual my girlfriend google is very verbose. (Sometimes I feel there should be utility like googlegrep or something : ) I am going through the excellent documentation from:

http://linux-ip.net/articles/Traffic-Control-HOWTO

LARTC.org

Its all a bit too much for me to handle at this point in time and I am a bit pressed for time.

Yes, havent worked much on tc / iproute2. In fact not much knowledge in networks in general.

Any help appreciated.


TIA

Regards,

Rajagopal

The best tool I have found for this is DummyNet, which is built into
FreeBSD. It was created to test protocol designs then adapted for
traffic management. However, I am not aware of any ports into Linux.

Hello Raja,

Take a look at xml-htb. It creates tc rules for you, it's actually
very easy. http://sourceforge.net/projects/xml-htb/

Thanks Bazy, News and Bob.

I will take a look into each option.

In the meanwhile I too have stumbled upon one which is more or less my scnario.

http://www.adamsinfo.com/bandwith-limiting-with-linux-tc-and-iproute2/


Only that I will have maybe one or two desktops which are used as test machines.

Thanks again for all your replies,

Regards,

Rajagopal
