Abstract :
In this paper, an active queue management (AQM) for TCP flows is designed by means of Lyapunov theory. To this end, we choose a non conservative Lyapunov candidate function which allows knowing how the marking/droping process should be done to achieve stability. This design leads to an AQM based on rate mismatch which insure responsiveness to the variation of the network´s characteristics, and is suitable even in case of non or full cooperation of the network users. Furthermore, the proposed AQM that we refer as LYAP was implemented under NS2 and compared to REM. The simulation results emphasized the effectiveness the LYAP.
