Instability effects of two-way traffic in a TCP/AQM system
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. (c) 2007 Elsevier B.V. All rights reserved.
