Hello , 
My application uses network resources extensively ; it 
should work under different bandwidth loads (according to the customer
bandwidth allocation) : under fixed 10 KB/sec , under fixedmax KB/sec,
and under fixed 30 KB/sec.

This means that the ADSL user,which uses this application, 
 is allocated a fixed bandwidth.

I need to test my application in this different bandwidth values. 
I do not have hardware tool to test this. 
Is there a tool for limiting the Network bandwidth by software, 
which can set an upper limit to the max bandwidth a station 
can transmit ? 

regards,
sting

You didn't say what Unix you used, so I'm going to assume it's
OpenBSD...

I believe the queueing facility of the OpenBSD Packet Filter
(pf) does soemthing like this, at least for outbound traffic:

search for "linux advanced rout(ing)|(er) howto"  using google or at 
tldp.org. Linux traffic control tools are sophisticated and powerful, 
but not not easily understood (at least by me).

What you want can be done, though.
