MUNOZ RODRIGUEZ, David et al. Shot Noise Modeling of Heavy Tailed Activity Periods. Comp. y Sist. [online]. 2006, vol.9, n.4, pp. 340-354. ISSN 1405-5546.

For web users, transmission activity is often described in terms of the number of file requests and file sizes that have a slowly decaying survivability function. In this article we model this line activity using a flexible shot-noise representation that enables us to analyze the infrared catastrophe effect introduced by the heavy-tailed characteristics. The proposed methodology is based on the α-stable characteristics of the traffic pattern. In addition, the effective bandwidth estimation of the proposed traffic model is presented. It provides a useful approach for the data network design and the admission control mechanism. Numerical results demonstrate the impact of the different statistical parameters on the spectral performance.
