    You can estimate dropped data segments by looking at the number of
    retransmits in each direction. It is not rare for TCP to re-send
    segments needlessly during slow start-based loss recovery, so it
    isn't a terribly accurate count, but at least it gives you some
    indication.

    As for lost ACKs... Nothing you can do there (fro tcptrace).
