Asynchronous transfer mode (ATM) traffic emulators have been designed for demonstrating the performance of various protocols and services in ATM networks under user-defined traffic conditions. Analytical tools and traffic measurements show that specific traffic conditions can be emulated by using the superposition of various stochastic processes. This paper presents a generic method for implementing stochastic processes using dedicated hardware and describes how this method has been used for implementing a real-time traffic emulator of ATM virtual channels.
