计算机网络流量的全局建模与预测

Global Modeling and Prediction of Computer Network Traffic

Stilian A. Stoev, George Michailidis, Joel Vaughan

摘要:

我们开发了一个概率框架的全球建模的流量在计算机网络。该模型将现有的单链路(流)流量模型与网络上的路由相结合,以捕获全局流量行为。它产生于一个有限的近似的流量波动的时间尺度和用户共享网络的数量增长。所得到的概率模型由高斯和/或稳定的无限方差分量组成。它们可以用某些“时空”随机场来简洁地描述和处理。该模型对模拟和真实数据进行了验证。然后,它被应用到预测流量波动未观察到的链路从一组有限的观察到的链接。此外,异常检测和网络管理的应用进行了简要讨论。

英文摘要:

We develop a probabilistic framework for global modeling of the traffic over a computer network. This model integrates existing single-link (-flow) traffic models with the routing over the network to capture the global traffic behavior. It arises from a limit approximation of the traffic fluctuations as the time--scale and the number of users sharing the network grow. The resulting probability model is comprised of a Gaussian and/or a stable, infinite variance components. They can be succinctly described and handled by certain 'space-time' random fields. The model is validated against simulated and real data. It is then applied to predict traffic fluctuations over unobserved links from a limited set of observed links. Further, applications to anomaly detection and network management are briefly discussed.
