| 摘 要： | 对因特网上采集的骨干链路流量的分组到达特征进行了研究,采用分组到达间隔时间的负指数分布拟合与独立性检验的方法,揭示了其不同于局域网流量的趋Poisson性质。提出了因特网骨干链路流量的类Poisson过程模型,对流量模型的到达间隔时间的分布函数及到达速率进行了讨论。利用仿真方法对流量模型与真实流量的排队分布及等待时间的分布进行了比较,结果表明,类Poisson过程模型与真实流量的排队性能有很好的一致性。

| Abstract: | The packets' arrival characteristics of Internet backbone traffic trace were researched.The packet inter-arrival time was analyzed through exponential distribution fitting and independency verification.The Poisson trend property was discovered,which was different from LAN traffic.The Poisson-like process model was put forward.The distribution of inter-arrival time and the arrival rate were discussed.The distribution of queuing and waiting time were compared in queuing simulation.The results suggested that t... |
