Mitigating Internet congestion

In a recent paper, we proposed a control strategy for active queue management in routers in order to alleviate Internet congestion. This work uses a congestion model which is nonlinear and contains a variable delay. The results are obtained by combining flatness-based control and model-free control. The article is illustrated with convincing simulations. The control law is easily implemented on a router.

This paper is entitled “Active queue management for alleviating Internet congestion via a nonlinear differential equation with a variable delay,” and will appear soon in “Annual Reviews in Control”. For the moment a preprint of the is available on ArXiv. It is co-authored by Hugues Mounier, Cédric Join, Emmanuel Delaleau and Michel Fliess. This publication is the result of a collaboration between the Université Paris-Saclay, Université de Lorraine, école nationale d’ingénieurs de Brest and école polytechnique.
