Abstract This work investigates and studies the performance of voice quality when sent over the ABR service in ATM networks. Sources can modify the rate at which they send traffic to the network based on the feedback carried by the Resource Management (RM) cells. This is achieved by changing the encoding level. As the contention increases in the network resources, (bandwith in this case), sources start to reduce the rate at which they generate and send traffic. The efficiency of the scheme under...

Abstract Asynchronous Transfer Mode (ATM) switching systems have been developed to support traffic patterns in telecommunication networks. The basic function of a switching element is to buffer cells that are destined for the same outlet. Two major buffering strategies are available for use in switching elements, input buffering and output buffering. Each buffering strategy affects the performance of the switching element, [sic] In this paper I have concentrated on...

Abstract Asynchronous Transfer Mode (ATM) switching systems have been developed in order to support the new traffic patterns in telecommunication networks. An ATM switching system is composed of identical basic switching building blocks called switching elements that have been arranged in a particular topology. The basic function of a switching element is to buffer cells that are destined for the same outlet. Currently, two major buffering strategies are available for use in switching elements,...
