What you are looking for is traffic shaping. You have two possibilities here.
Free and commercial:
FREE: Currently in the 2.2.1 kernel docs. Though I can't confirm this,
it looks like this shaper CANNOT do different shaping based on
the traffic type (TELNET, WWW, etc)
/usr/src/linux/Documentation/networking/shaper.txt
--
Gotchas:
The shaper shapes transmitted traffic. It's rather impossible to
shape received traffic except at the end (or a router) transmitting it.
Gated/routed/rwhod/mrouted all see the shaper as an additional device
and will treat it as such unless patched. Note that for mrouted you can run
mrouted tunnels via a traffic shaper to control bandwidth usage.
The shaper is device/route based. This makes it very easy to use
with any setup BUT less flexible. You may well want to combine this patch
with Mike McLagan <[EMAIL PROTECTED]>'s patch to allow routes to be
specified by source/destination pairs.

* BUGS:
* Downing the interface under the shaper before the shaper
* will render your machine defunct. Don't for now shape over
* PPP or SLIP therefore!
* This will be fixed in BETA4.

COMMERCIAL: Check out the Bandwidth Manager from Emerging Technologies.
Though it costs $500, this product WILL shape traffic
based on traffic type (TELNET, WWW, etc, )
