研究拥塞Internet连接的两个模型

Two Models for the Study of Congested Internet Connections

Ian Frommer, Eric Harder, Brian Hunt, Ryan Lance, Edward Ott, James Yorke

摘要:

在本文中,我们介绍了两个确定性模型,旨在捕捉拥塞的互联网连接的动态。第一个模型是一个连续时间模型,它将微分方程系统与其中一个状态变量的突然变化相结合。第二个模型是一个离散时间模型,其时间步长是从系统中自然产生的。从这些模型的结果显示出良好的协议与著名的ns网络模拟器,优于以前的,类似的模型的结果。这在很大程度上是由于使用突变来反映丢失数据包的影响。我们还讨论了该模型在网络流量状态估计中的潜在用途。

英文摘要:

In this paper, we introduce two deterministic models aimed at capturing the dynamics of congested Internet connections. The first model is a continuous-time model that combines a system of differential equations with a sudden change in one of the state variables. The second model is a discrete-time model with a time step that arises naturally from the system. Results from these models show good agreement with the well-known ns network simulator, better than the results of a previous, similar model. This is due in large part to the use of the sudden change to reflect the impact of lost data packets. We also discuss the potential use of this model in network traffic state estimation.
