yes, you are right; but the parameter m is supposed to represent the number
of packets that might have been transmitted during the idle time for the
specific queue. Hence, the queue service rate should be used.

If you have time check http://www.aciri.org/floyd/papers/early.pdf page
20-21 and dsredq.cc file (diffserv module, ns), function setPTC and enque.
