Abstract

A nonlinear dynamic model combined TCP and UDP under RED mechanism has been presented in this paper by modified a previously developed one. We linearized the model and added the feedback control mechanism that is introduced by RED, and then educed a proposition. Based on this proposition, we analyzed the impact of several parameters on the system stability, and we can present design guidelines for choosing network parameters that lead to stable operation of the linear feedback control system. We also performed simulations using NS2, and the results show that our analysis is suitable.
