Re: restrict bandwidth usage

Hi,

Well, I guess you are speaking about the bandwidth burst rate for each PC. 
At any given point of time, you can restrict your PCs to go up to a maximum 
of 75% of your bandwidth. You should be looking at the Linux traffic shaper 
for more details on this. 

There are different tools for doing this. One of them is the tc tool - 
Traffic control (http://www.rns-nis.co.yu/~mps/linux-tc.html)

Or you can compile the LQL(Linux QoS Library) with the kernel for achieveing 
this(http://www.coverfire.com/lql/)

See some of the other links:
