Passive control of chaos in TCP/AQM networks with time delay

Chaos occur in a TCP (transmission control protocol)/AQM (Active Queue Management) network under certain conditions, which often lead to the network oscillations and mass data packet loss. To control these undesirable chaotic oscillations, a passive control law is presented in this paper, which transforms the network system into an equivalent passive system. The equivalent system can be asymptotically stabilized at its equilibrium points. Simulation results show the effectiveness of the control law.
