CONGESTION CONTROL OF TCP/AQM NETWORKS USING PREDICTIVE CONTROL AND ON-LINE LINEARIZED MODELS Teresa Alvarez, Anuar Salim and Mohammed Bolajraf Department of Engineering Science and Automatic Control, School of Computer Engineering, University of Valladolid Valladolid, Spain [email protected], [email protected], [email protected] ABSTRACT Internet users rely on the good capabilities of TCP/IP networks for dealing with congestion. Classic algorithms, such as drop tail or even RED, do not give good results under many situations. The network delay and the number of users fluctuate from one moment to the next. Predictive control can deal with these conditions so performance can be improved. This paper presents how predictive control, with on-line linearized models, performs better than PID or classic predictive control when dealing with control …
