Abstract--We introduce an alternative approach to con-
gestion avoidance and control, which has the potential to in-
crease efficiency and fairness in multiplexed channels. Our
approach, Bimodal Congestion Avoidance and Control, is
based on the principles of Additive Increase Multiplicative
Decrease. It is designed to better exploit the system prop-
erties during equilibrium, without trading off responsive-
ness for smoothness. In addition, it is capable of achieving
convergence to fairness in only two congestion cycles. As
a result, both efficiency and fairness are improved, respon-
siveness is not degraded, and smoothness is significantly im-
proved when the system is in equilibrium. We provide a the-
oretical analysis for both static and dynamic environments
and we discuss the potential of our approach for packet net-
works. Our experiments confirm that Bimodal Congestion
Avoidance and Control as a component of the Transmission
Control Protocol outperforms the traditional scheme.
