- Voice and data applications in differentiated service intranets Marlenne Angulo Bernal Marco A. Turrubiartes Reynaga Deni L. Torres-Roman Marco Antonio Argumedo Ledón Ingeniería Quality of Service Voice over IP networks Differentiated Services One of the options that telephonic systems have, in order to optimize the required bandwidth, is to migrate tostatistical multiplexing systems. These multiplexing schemes also allow the convergence with current datacommunications systems. This work is based on the interconnection of telephonic systems through the datanetwork using digitalization and voice compression techniques. The optimization of the resources is achievedusing the voice compression standard of 8 kbps instead of the 64 kbps standard, thus introducing differentiatedservices in IP networks. The performance of the voice packets is improved in terms of delay and packet losses. Theresults presented here obtained by means of computer simulations using COMNET. Real telephonic trafficinformation acquired for several months at the UABC was used. This allowed the consideration of effects such as:busy hours and variable call duration. The performance of the system was evaluated, obtaining very satisfactoryresults in terms of resources utilization. 2004 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47420106 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.1 Vol.2
