RESUMO

Broadbend Integrated Services Digital Networks (B-ISDN) are characterized by their flexibility of integrating a variety of traffic sources such as, voice, data and video. Congestion control of these networks is studied in this work. Through simulation of traffic sources, it have been possible to explore statistical multiplexing gain reached by the Asynchronous Tranfer Mode (ATM) utilization. We present the congetion control phases and results concerning the Bandwidth Allocation and Admission Control phases. The Bandwidth Allocation is used by the Admission control to decide a new call acceptance. We also present, the simulation results concerning the Bandwidth Allocation for each traffic source and a comparison between some admission criteria proposed in the literature and simulation results.
