Abstract

The ATM (Asynchronous Transfer Mode) is the switch and multiplexing chosen by CCITT for the broadband ISDN network and has been widely applied in the industrial. The objective of this project is to address the most important issues concerned with the implementation of a switch. In this report, we focus our discussion on Software Architecture and ATM Scheduling. For a network software implementation, an appropriate software architecture must be chosen. We will discuss the three software architectutes used in the network software implementation and make the justification for them. The scheduling disciplines of the switching nodes, which control the order in which cells are transmitted, determine how cells from different connections interact with each other. The scheduling discipline has the great affect on the switch's performance. In this report, we will present guildience to choose a cell scheduling algorithm for an ATM switch.
