Abstract

In this article, a way to employ the diffusion approximation to model interplay between TCP and UDP flows is presented. In order to control traffic congestion, an environment of IP routers applying AQM (Active Queue Management) algorithms has been introduced. Furthermore, the impact of the fractional controller PIγ and its parameters on the transport protocols is investigated. The controller has been elaborated in accordance with the control theory. The TCP and UDP flows are transmitted simultaneously and are mutually independent. Only the TCP is controlled by the AQM algorithm. Our diffusion model allows a single TCP or UDP flow to start or end at any time, which distinguishes it from those previously described in the literature.

摘要

本文提出了一种利用扩散近似来对TCP和UDP流之间的相互作用进行建模的方法。为了控制流量拥塞，引入了应用主动队列管理（AQM）算法的IP路由器环境。此外，还研究了分数控制器PIγ及其参数对传输协议的影响。该控制器是根据控制理论精心设计的。TCP和UDP流同时传输且相互独立。只有TCP由AQM算法控制。我们的扩散模型允许单个TCP或UDP流在任何时间开始或结束，这使其有别于文献中先前描述的模型。
