Researches around the world agree with the presence of heavy-tail behavior in almost all the data traffic’s metrics, such as connection arrivals, file sizes, central processing unit (CPU) time demands of UNIX processes, etc. As a result, during the next few years, heavy-tailed distributions will play a principal role in the modelling and developing of telecommunications systems. Due to the nature of data traffic, researches demand a discrete heavy-tail distribution, perfectly well described, that enables them to reflect the impact of the two states present in all digital systems (on/off, successful/failed, connect/disconnected, enabled/disabled) in the tail decay. At the present time, there is no distribution with this high degree of flexibility. This thesis completes the description of the discrete heavy-tail distribution introduced in [24] by getting their moments and variance derived from a rigorous generating functions analysis. It validates the model’s heavy-tail nature through mean excess functions and some related plots such as the Quantile-Quantile or Probability-Probability plot. Also, the model’s stability and their match with the Pareto distribution are investigated. This work concludes with a discussion about the initial conditions influence in the model’s tail decay.textoinfo:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0Area::INGENIERÍA Y TECNOLOGÍA::CIENCIAS TECNOLÓGICAS::TECNOLOGÍA DE LAS TELECOMUNICACIONESTesis de maestría
