abstract = {Considering four popular Active Queue Management
(AQM) schemes, we demonstrate by simulations that loss and delay of
acknowledgement (ACK) packets, due to congestion, may significantly degrade the
stability of a TCP/AQM system. We demonstrate that giving priorities to the ACK
packets can stabilize the system.}
