Internet中的相变现象及一种新的相变业务流模型

Phase Transition Phenomena in the Internet and a New Phase Transition-Based Traffic Model

本文从宏观的角度阐述了Internet的网络行为和业务流相变现象的特性 ,讨论了相变现象的存在对于网络系统的行为和控制带来的影响 ,并提出了一种改进的能够真实地反映出汇聚业务流的基本统计物理特征的网络业务流模型 。

The paper expatiates on network behavior of Internet and the characteristics of the traffic phase transition phenomena from macroscopic viewpoint.The effects on network system behavior and control algorithm arising from the existence of phase transition are also discussed.Finally,an improved network traffic model based on these phase transition phenomena,which can reproduce the basic statistic physical property of aggregated network traffic,is presented.Simulation results validate our improved network traffic model.
