before you go any further, download and read the Van Jacobsen/Karels
paper "Congestion Avoidance and Control":
ftp://ftp.ee.lbl.gov/papers/congavoid.ps.Z
in a sliding-window protocol like TCP the arrival of an ack lets the
sender know that the receiver has buffer space for the next packet and
permits the sender to transmit more data; the acks form a kind of
"clock" that signals that data has left the network and that there is
room for more.
