asterisk users - Jun 2003 - Using Linux traffic shaping to prioritise SIP/IAX traffic?

Hi,

Has anyone done anything with the Linux advanced routing stuff to give
SIP and IAX traffic priority?

What I have in mind is a high-pri queue for voip traffic, all the rest
in another queue that gives way to the VOIP stuff.

Thanks,
Steve

When the "tos" option is set correctly (to "nodelay"), the
default
queueing in recent kernels already does that, because the pfifo_fast
queue is used (if I recall correctly).

Linux kernel by default prioritizes traffic if
the packet has some TOS bits set. so a standard
linux router should do a basic traffic shaping.

Of course, more complex rules could be made...

but if the *outside* world don't do traffic
shaping (or just ignore TOS bits), the priority
you set works only in your net, outside is
not guaranteed they will do what you want to ;)
