How to distribute bandwidth across clients.

Is there any way to distribute bandwidth across 100 clients connected to internet through squid proxy server?

For example, if i want to divide 30Kbs to every client. And to some clients i want to allot 50KBs?

Or any iptables solution for that?

Cheers!!

Why would you want to do that? That's just going to waste the majority of the bandwidth you're paying good money for. If someone isn't using their strict 30kbps allocation, it just goes begging?? Use something like Delay Pools in squid which will allow for suitable amounts of bursting within limits, meaning that accessing small articles, up to a few meg will be able to get it nice and quick. If they start sucking down an iso then other more bursty traffic can leapfrog it to keep good speeds.

Thank you,

What i really want is:

I want to ensure the minimum bandwidth for each user.. lest say 30KB's for every client if they all use bandwidth simultaneously. And distribute the available bandwidth of offline clients to online clients.

And delay pools are for http traffic.. what to do for other traffic?

Cheers!!

well you said you were going via squid. What else are you actually doing? You might rather check a shaping script like the really nice wondershaper. This is a script to implement a generic htb setup, which is the tool you'd generally turn to to be as strict as you want so also may be worth reading in its own right http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm

Note that proxied traffic will come from the address of the proxy, not the client, so you'd need to be applying lower level controls before the proxy, not after it.

What you want, as acid pointed, is traffic shaping. If you want to write your own scripts, or see how its done, I suggest you look at LARTC:
