Modelagem de tráfego VoIP utilizando misturas gaussianas ajustadas por algoritmo de maximização de esperança e comprimento de descrição mínimo. Revista de Informática Teórica e Aplicada: RITA, Porto Alegre, v. 20, n. 3, p. 112-129, 2013.e- 2175-2745http://repositorio.bc.ufg.br/handle/ri/19345The increase in the number of applications that generate VoIP (Voiceover IP) traffic requires that suitable models for this kind of traffic be used to bet-ter dimension and predict network resources. In this paper,we propose the applica-tion of Gaussian mixture adjusted by an EM algorithm (Expectation-Maximization)with selection of classes using the principle of Minimum Description Length (MDL-Minimum Description Length) in order to describe VoIP traffic. Real VoIP traces werecollected and synthetic time series were generated according to these data. The propo-sed algorithm is compared to the EM algorithm and the MDL (Minimum DescriptionLength) based algorithm in terms of performance in modelingthe considered VoIPtraffic traces.porAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Artigo
