Dynamical Bandwidth Control?

Sirs,
I am searching a tool to dynamically control bandwidth in my network.
Suppose I have a network composed of some subnets. I don't want
that one single subnet takes control of the whole bandwidth thought
the gateway. There are some solutions like iproute with cbq etc.
But I would like to have the flow control of the network, through
my gateway, dynamically handled. That means, if subnet 1 needs all
the bandwidth for less than 1 minute, that ok. The burst of 1 minute
is tolerated. But after this 1 minute I must reduce the bandwidth
it is using until it reaches a minimum that is fair to the others.
I saw many Papers on the net with plenty of algorithms to handle
queues an so on.
Is there a software for a a Linux router that solves my problem? If
doesn't, what do we have that is closest to what I need?

main(){int j=1234;char t[]=":@abcdefghijklmnopqrstuvwxyz.\n"
,*i = "iqgbgxmlvivuc\n:wwnfwsdoi"; char *strchr(char *,int);
while(*i){j+=strchr(t,*i++)-t;j%=sizeof t-1;putchar(t[j]);}}

I found a software at http://www.etinc.com/

Does anybody know anything about it? Is it good and flexible? Works fine under
linux box?

What you are looking for is called traffic control. The binary for setting
things up is called "tc", and there is a large document on how to set it
all up at www.lartc.org


Yes, tc has lots of papers and accademic docs. Not too much on the "how do
I do this?" department. lartc.org is a good starting point, though.


luck

I am using tc and htb, this works fine and is not that difficult to
configure. There are enough examples in the internet, simply fire google
with something like"htb linux iptables example"...

try HTB

Thnx everybody who helped me on this subjetc. htb seems to solve my
problem.
