This project, which studies the problem of Internet congestion in large scale under the demand of huge amount of data through the Internet, is a fundamental research in both theory and application. For the purpose of congestion control, the resource allocation is optimized by means of analysis on nonlinear dynamics of time-delay systems. Based on the study on the following three scientific problems: (1) the mechanism of large scale Internet congestion in terms of dynamics of time-delay systems; (2) the equivalent time-delayed dynamical model of large scale Internet congestion; and (3) online learning-based control of large scale Internet congestion, we propose to further understand the origin of large scale Internet congestion and build up the equivalent time-delayed dynamical model of Internet congestion. As application, we plan to design the online learning control strategy for suppressing the propagation of Internet congestion and consequently provide a systematic way of modeling, analyzing and controlling the large scale Internet congestion. In this project, the research on the dynamical behavior of time-delayed systems plays the fundamental role and the key problem is building up the equivalent time-delayed dynamical model of Internet congestion control system. The main target of this project is to uncover the mechanism of propagation of congestion inside/across Internet layers and to build up the equivalent time-delayed dynamical model of congestion propagation as well as to design the online learning control algorithm. These results will help us to enhance the reliability of the Internet and consequently extend the scope of application of the Internet.
