The design of an object-oriented simulation tool for evaluating ATM network resource control schemes

Changing the algorithmic components of ATM equipment such as ATM switches, requires full access to the switch control software, which is not available in most commercial products. Hence, most researchers still resort to simulation in order to evaluate new traffic control algorithms. This paper presents the architecture of an ATM simulator that operates at the call level, exposes the power of such a tool in evaluating different control architectures for ATM networks, and presents the status of a prototype implementation. ATM simulators based on the proposed architecture include a Web-based component (Java applet) which acts as user interface. This component enables tele-training and dissemination of important simulation results to remote sites.
