ATMTraP: an asynchronous transfer mode traffic and performance measurement tool

The analysis and development of ATM network traffic control algorithms is often performed using theoretical traffic models. Algorithms for traffic shaping, policing, flow control, and switch architectures have been proposed based on these models. While the models help to obtain preliminary solutions, the success and validity of the proposed algorithm will be a function of how close the assumed models resemble real traffic patterns. The paper presents ATMTraP, an experimental prototype asynchronous transfer mode traffic and performance measurement tool which could be used in the characterization of sources and elements that form the ATM network. ATMTraP has been used in the Nectar Gigabit Testbed to collect preliminary traffic statistics from sources, such as, a Cray C-90 supercomputer, Sun workstations, and an iWARP systolic array.
