Asynchronous Transfer Mode (ATM) networks provide guarantees on quality of service by first determining the availability of the required network resources and then reserving these resources for the duration of the application call. The Call Admission Control components of the network is responsible for these functions. This paper is concerned with the calculation of bandwidth requirements for traffic traces obtained from measurements taken from a wide area ATM testbed network. Two kinds of traces are considered: IP applications traffic and jittered constant bit rate traffic streams that have traversed multiple switching hops of the network. The actual bandwidth requirements are computed using simulation and then compared with the equivalent bandwidth theory for on-off sources.
