A fluid-based model combined TCP and UDP under RED mechanism has been presented in this paper based on a previously developed one. We linearized the model and added the feedback control mechanism that is introduced by RED, and then educed three propositions. Based on these propositions, 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.
