Abstract
As ATM cells pass through an ATM network, they experience a variable amount of delay as a result of queuing and switching delays at the switches. Real-time applications need a low intercell arrival time variance or their real-time needs will not be meet. Therefore, in order to analyze the end-to-end performance of real-time applications or to estimate the quality of service parameters (QoS) that an application must negotiate in-order to meet certain performance requirements, it is important to form an accurate estimate of the end-to-end cell delay variation. We describe our approach to benchmarking the variation of inter-cell arrival times or jitter in this paper. We present experimental results of actual jitter measurements on the FORE ASX200BX switch, using the HP OC3Port cell analyzer and a Pentium workstation running Linux. We also present a quantitative analysis of how this variation compares with the effects of the ATM network card driver being used at the workstation, which is r...
