Hello, If you just wanna reduce the b/w pipe per server wrr could be a simplistic implementation that would work. For real functionality see htb which works like a charm. For something more complex see cbq.

Hello Jean, For all that i know your tcng config would be perfectly fine. I will mail you my 4000 node config. Please try the same out and lemme know it if works for you.

Hello everyone! I would like to do a linux router to limit the connection for some servers to 1 mbs per server. [SERVERS] ---> [Linux "1MBS per server" router] ---> ((((Internet)))) I did some searches about routing and bandwidth on the net and the solution seems to be ''tc''. Well, ''tc'' is not very easy to understand so I tried ''tcng''. I installed it and it seems to work fine (able to generate the ''tc'' rules and tcsim is working). Now, my question is what type of configuration do I need? I read some doc about tcng and I saw the "fifo", "tbf", "SLB"... I need a rate so it''s not "fifo". How do I configure the others? Thanks for your help! Jean-Francois _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
Hi!
I have done that script to test my router :
#include "fields.tc"
#include "ports.tc"
#define INTERFACE eth0
#define LIMITEDRATE 1kBps
dev INTERFACE {
egress {
/* In class selection path, the filters come first! DSmark */
class ( <$AB10CL> ) if ip_dst == 10.1.1.10 || ip_src ==
10.1.1.10;
class ( <$AB11CL> ) if ip_dst == 10.1.1.11 || ip_src ==
10.1.1.11;
class ( <$AB12CL> ) if ip_dst == 10.1.1.12 || ip_src ==
10.1.1.12;
class ( <$other> ) if 1 ;
/* section in which we configure the qdiscs and classes */
htb () {
class ( rate 10kBps, ceil 10kBps ) {
$AB10CL = class ( rate LIMITEDRATE, ceil LIMITEDRATE )
{ sfq; } ;
$AB11CL = class ( rate LIMITEDRATE, ceil LIMITEDRATE )
{ sfq; } ;
$AB12CL = class ( rate LIMITEDRATE, ceil LIMITEDRATE )
{ sfq; } ;
$other = class ( rate 1kBps, ceil 1kBps ) { sfq; } ;
}
}
}
}
I have plugged my machine behind the router but I see no difference when
I download :-(
What is wrong with that script?
If this is not working, I''ll try wrr.
Thanks!
