MUNOZ-RODRIGUEZ, David et al. Heavy Tailed Network Delay: An Alpha-Stable. Comp. y Sist. [online]. 2006, vol.10, n.1, pp.16-27. ISSN 2007-9737.

Adequate quality of IP services demands low transmission delays. However, packets traveling in a network are subject to a variety of delays that, in real-time applications, severely degrade the quality of service (QoS). This paper presents a general end-to-end delay model suitable for a multi-node path in the presence of heavy-tailed traffic. The proposed methodology is based on an alpha-stable random variable description. This allows us to define a network processing measure that relates the delay spread to the heavy tail characteristics of the traffic, the number of nodes in a route, and the processing speed at the nodes.
