Modelo analítico para el dimensionado de la RPT/RDSI con tráfico de voz y acceso a Internet

Abstract

Internet access through the public switched telephone network, PSTN/ISDN, produces changes in the characteristics of traffic managed by this kind of networks. Under this situation, traditional network dimensioning using Erlang model results excessively optimistic. This article develops a simple model to approach traditional methods to current PSTN/ISDN traffic features including the effect of call repetition. The analytical model obtained for traffic dimensioning is validated with simulation models, and have been integrated in tools for design and dimensioning of PSTN/ISDN networks.
