asterisk users - Jan 2005 - Linux Bridge + QoS Shaper HOWTO available

I've created a pretty complete HOWTO on creating a Linux Bridge (using 
Fedora) to shape LAN <--> WAN traffic. It includes installation 
instructions, a script to configure the bridge (which you install as a 
service), and 2 scripts to configure the network interfaces using traffic 
control.

If anyone has any questions or feedback I'm very interested. This 
configuration has evolved over the past 6 months and is pretty tweaked. 
The highest priority traffic in my config, is of course, IAX2.

This looks really nice!

I know that you can't really shape inbound traffic, but I think the 
killer shaper would start delaying TCP traffic as soon as total incoming 
bandwith utilization hits 75%. Unless somebody floods your link, it 
should work pretty effectively.

I've got no clue if it's possible with unpatched kernels... apparently 
IMQ can do this but you need to fiddle around with your kernel... drag :)

Cheers,
Jean-Michel.

Does your script work for SIP too? Only for IAX?

 

I'd like to put two of your bridges in my setup - one between the local
LAN and the net, and the other at our branch office between the LAN and
WAN there.

 

But I need to be able to allow for sip to be QOSed, as we currently have
an asterisk server at the remote office, and sip clients here.

Yeah that's what is going on in my scripts. I sacrifice ~ 25% bandwidth
in hopes of becoming in charge of the bulk of queueing (instead of the
ISP). It actually makes a big difference, in my tests. I was able to
soak upload and download and still run Citrix and Video and VoIP
smoothly. If I didn't back off the speed, it was horrible. So IMO it is
truly worth the sacrifice in bandwidth.

Howdy!  I'm VERY interested in your HOWTO... but the link you have, 
below, times out.  Any chance you could mail me the HOWTO, or point me 
to a new link?

Thanks much!
