Abstract. We investigate the interaction between Transmission Control
Protocol (TCP) and an Active Queue Management (AQM) router, that
are designed to control congestion in the Internet. TCP controls the
sending rate with which the data is injected into the network and AQM
generates control signals based on the congestion level. For a given TCP
version, we define the optimal strategy for the AQM router as a solution
of a nonlinear periodic optimization problem, and we find this solution
using a linear programming approach. We show that depending on the
