limit outgoing bandwidth for an application

How would i go about limiting outgoing bw from my computer for a specific
application ?

I know how to do it with a cisco router but not how to do it with Linux.

Actually i would like to police traffic so that outgoing http and rtp
requests would get as much bandwidth as needed while some specific
application would only be provided with a specific maximum amount of
bandwidth !

Have anyone done that ? or can this be done at all ?

Thanks in advance

Although i'm not entirely sure how to do this I can point you in the right
direction. There are going to be a few problems I can think of off hand.
Using iptables (http://www.netfilter.org) you can limit traffic based on a
particular uid or gid and in conjunction with that and specifying the
destination port you should be able to properly limit the traffic. The
iptables targets you are probably interested in are LIMIT and ULOG (a
better LOG target replacement).

How would you do this with a Cisco router? Are you talking about layer 7
classification?

If your looking for layer 7 classification, then you should check this
out http://l7-filter.sourceforge.net/ other wise you should check the
owner match ability of iptables....

Good Luck!

See Trickle http://freshmeat.net/projects/trickle/?topic_id=87
or Linux Bandwidth Arbitrator
http://freshmeat.net/projects/arbitr...c_id=253%2C150

I was kinda more interesting in policing and shaping the traffic not just
denying specific traffic ? will netfilter do that for me as well ? or am i
supposed to look into TC ??
