How to distribute Network bandwidth between Network clients dynamically ?

Hello all,

I am running a IPTABLES + Squid environment.

I want to distribure Network Bandwidth (mostly internet connectivity) over no. of clients dynamically. By means of dynamically,

e.g.
Total B/w : 1 mbps
If no. of clients = 50 then, each client can use max 1mb/50 = 20 kbps
If no. of clients = 20 then, each client can use max 1mb/20 = 50 kbps

Note : No. of clients should be decided runtime without user interaction.

How can i achieve this using iptables rules ?

Any pros/cons for this type of environment ?

I am start searching on the net for same, but your help will be definitely useful.

Thanks in advance,

with all due respect that's a horrible horribile way to allocate bandwidth.

if you do that you'll waste about 90% of your potential bandwidth at any one time. if one user isn't currently downloading anything why should that bandwidth not be used by another use? that's why your ADSL service has a contention ratio. Would you rather have a dedicated 100k link or a shared 10mb link with 100kbps guarenteed?

traffic shaping at ip level is reasonably easily done via tc / htb: http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm and within squid you have delay pools to explore. are you only interesting in proxied web traffic?
