Hello!

I'm pretty new to ipfw with respect to using dummynet pipes and 
queues for traffic shaping. For the life of me, I can't figure out
how to do something I want:

How to force my interface to burst its traffic.

That is, I want a pipe that  has a delay of A and
a bandwidth of B but will stall itself at the *end* of 
a count C of slots/bytes/whatever for a defined waiting period D
and then continue.

Do I want a configurable queue delay maybe?

The ipfw/dummynet docs talk about the delay caused by a deep queue
but doesn't mention a way to explicitly set a delay like you
can for pipes.

Is there any way to accompish this with multiple pipes and queues
perhaps?

Thanks,

Charles
