I think if I specify something like upperlimit(x, n, y) then tcp connections that are in that queue will get at most x for n milliseconds and then y for the rest of the time. If in the meanwhile another tcp connection comes, then even this second connection get at most x for n milliseconds and then y. Service curve is something related to the state, not to the queue.

i found kenjiro chos paper on altq really useful to understanding how this stuff behaves. dlg
