Bimodal Congestion Avoidance and Control
Paul C. Attie, Adrian Lahanas, and Vassilis Tsaoussidis
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.
