  Active Queue Management (AQM) for mitigating Internet congestion has been
addressed via various feedback control syntheses, among which P, PI, and PID
regulators are quite popular and often associated to a Smith predictor. Here,
to better account for the many uncertainties, like the round trip time or the
number of TCP sessions, the above controllers are replaced by an intelligent
proportional controller associated to Model-Free Control (MFC) and by
forecasting techniques derived from a new approach to time series. Several
computer simulations via a well accepted linear modeling, where the delay is
assumed to be constant, are presented and discussed.
