Abstract
Con el desarrollo del protocolo de red IP se ha generado un crecimiento explosivo de Internet en los últimos diez o quince años, que ha llevado a la proliferación de múltiples servicios de comunicación, dada la naturaleza de este protocolo se hace necesario implementar mecanismos que permitan asegurar la calidad de servicio a los usuarios finales. El presente artículo presenta un sistema de evaluación en línea efectiva en la vigilancia y medición de la calidad percibida de la voz sobre IP consistente en el tiempo. El modelo presentado combina el control estadístico de procesos y los métodos objetivos de estimación de la calidad percibida de voz. Para esto se ha implementado el grafico de control multivariable T_ de Hotteling y el método objetivo no intrusivo de estimación de la calidad percibida de voz “Modelo-E”.
The development of the Internet Protocol ( IP) it´s generating an explosive growth of Internet and that have taken the proliferation of multiples services of communication. But this protocol needs to implement mechanisms that allow to assure the quality of service to the end users. The present article presents a system of effective on-line evaluation in the surveillance and measurements of the perceived quality of the voice on IP consistent in the time. The presented model combines the statistical control of processes and the objective methods of estimate of the perceived quality of voice. For this it has been implemented Multivariable Control Chart T_ de Hotteling and the perceived method for voice quality prediction to voice over IP.
