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.

“…In order to avoid jitter, the instability of the network is learned. Stochastic methods [1][2][3][4][5][6][7] are traditionally used to analyze the network but several papers proposed deterministic nonlinear modeling and analysis [8][9][10][11].…”

Due to the quality of some services, jitter should be minimized in the network. To avoid jitter, the authors adopt a discrete time feedback system model for a TCP (Transmission Control Protocol) network with RED(Random Early Detection) in a tandem network. On the basis of this model, jitter is known that it is caused by the instability of the network. In order to analyze the instability, the model while one system parameter gradually changes and other system parameter keep still is simulated. Then it is obtained that bifurcation behavior occurs, leading to chaotic behavior while the system parameter increases. Hence, the new router should be set accurately when it is connected to the existed network. Moreover, it is asserted that our work will have instructive impact on configuring the router.
