The Chaos State of Internet and Coping Method

Abstract

In this paper, a deterministic nonlinear model, i.e., the TCP-RED feedback system is adopted to simulate a complex computer network. The phase-space reconstruction is applied to reveal the hidden information of rate which could be obtained from the Internet easily. In addition, the maximum Lyapunov exponent is applied to judge the stability of the TCP-RED feedback system. The research demonstrates those two different parameters affect the system’s stability. To avoid the system evolving into chaos state, the parameters of routers must be configured properly.
