RESUMO

The growth and popularization of the Internet allied with new technologies and the emergence of voice communication links faster to provide an infrastructure converged voice and data known as Voice over IP (VoIP â Voice over Internet Protocol). The main advantages are: reduction in the costs of communication and the use of the service of voice with data applications. The internet was not designed with the intention of supporting real-time information, as it uses the model of best effort that offers no delivery guarantee and limit the delay of packages. However, VoIP applications that require delivery of packages of voice with delays and losses limited. Therefore, it is necessary a level of conversation using VoIP compared to traditional telephony networks. The need of using VoIP in different network architectures requires that the environment should not have any performance degradation. In this work, we present a VoIP performance evaluation model based on the stochastic models using distributions poly-exponentials
