Abstract

Asynchronous Transfer Mode (ATM) is a high-speed networking technology designed to support real-time applications such as voice and video over both wired and wireless networks. This type of network is being used by medium-to-large organizations and the Internet service providers as backbone network to carry data traffic over long-distance with a guaranteed quality of service (QoS). The guaranteed QoS is achieved through a point-to-point link between end users. While the performance of ATM network over wired network has been studied extensively, the performance of real-time traffic over an ATM-Wireless extension has not been fully explored yet. It is useful to be able to compare the performance of ATM network with and without wireless extension against various network performance metrics to find out the effect of wireless extension on system performance.

Modelling The Network

Figure 1 shows the high-level view of ATM backbone network model. We model the network by considering a star topology with four subnets (Northeast, Northwest, Southeast and Southwest). Figure 2 shows the network topology for each subnet where nodes are linked to ATM switch in a star configuration (point-to-point link). A screenshot of ATM Switch configuration is shown in Figure 3. We use OPNET Modeler 17.5 (a credible network simulator) for network modelling and simulation purposes (Fullmer & Garcia-Luna-Aceves, 1997). The various network configurations are described next.
