摘要

本文通过对已有模型的改进，提出了一个RED机制下TCP和UDP复合的非线性动态模型。对模型进行线性化处理，加入RED引入的反馈控制机制，并提出了一个建议。基于这一命题，我们分析了几个参数对系统稳定性的影响，并给出了使线性反馈控制系统稳定运行的网络参数选择的设计准则。我们还使用NS2进行了仿真，结果表明我们的分析是正确的。

A control theoretic analysis of mixed TCP and UDP traffic under RED based on nonlinear dynamic model

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.
