Abstract :
Internet congestion algorithm decides the queue sizes and quality of service (QoS) of network. Based on the mechanism of Internet congestion control, a new active queue management (AQM) algorithm based on the fuzzy logical controller (FLC) is presented. When the system states are far off the equilibrium, a sliding-mode controller (SMC) is applied to control the states returning the neighbor of the equilibrium in a limit time. For decreasing the vibration of SMC, a state feedback controller (SFC) is gradually used to replace SMC in a small region of the origin. A fuzzy logical controller (FLC) is introduced to realize the switch between SMC and SFC. Finally, simulations show the validity of the new AQM algorithm
