TCP ABC is ``... a small modification to the way TCP increases
    its congestion window.  Rather than the traditional method of
    increasing the congestion window by a constant amount for each
    arriving acknowledgment, the document suggests basing the increase on
    the number of previously unacknowledged bytes each ACK covers.  This
    change improves the performance of TCP, as well as closes a security
    hole TCP receivers can use to induce the sender into increasing the
    sending rate too rapidly.''[1]

I wonder if the code from DragonflyBSD[2] would be of interest for NetBSD?
