Yes, I see. My last experience with things like this suffered a little from a slightly underfunctional implementation of bandwidth control (and using dummynet/FreeBSD was not an option). I only had control over the outgoing queue on the external interface, so I tried slowing down slow start by limiting the acks from teh destination to the source of the transfer based on calculations with packet sizes and -rates (which seemed to be more than a little unreliable). [Perhaps I could construct a scenario with some more interfaces, where limiting the outgoing rates would be easier, but that would be too far fetched for now]. So my problem in short: How much do I have to limit acks in the direction with the lower bandwidth in order to control the usage of the other direction? This is a little away from the original thread, but I just would like to know (might come in handy some time and perhaps I can "ptimize" my old "solution" a little with other people's experience).
