I guess the integrator used in queue monitors is provided for this
purpose. However I'm not clear how you can use it, and I've not seen any
examples scripts or test suites using it. Try to look at integrator.{h,cc}
and ns-lib.tcl to find out how to use it. It'll be great if you can write
a little script as a demo and we'll put it in the tcl/ex directory.
Thanks!
