RESUMO

The behavior of VoIP traffic in network links is addressed in this work. VoIP applications have strict requirements for quality of service (QoS) that should be provided for in the network design. In this sense, the Markov Modulated Poisson Process (MMPP) is displayed as model of process of arrivals that is appropriate to characterize the behavior of superposition of VoIP traffic sources. It is taken into account that VoIP applications use the mechanism Suppression of Silence to save bandwidth, which makes the traffic very variable and with bursty arrivals. In order to analyze the behavior of the link, the MMPP/M/1 queue model is used. To evaluate the viability of the model, comparative studies were made with results of the ns-2 simulator
