The optimal test traffic for analysis of CDV characteristics on ATM network

Several studies have been done to provide results for the estimation of the cell delay variation (CDV) accumulation characteristics on ATM systems and network. Because most of these studies were done by simulation and analytical modeling, we have to recognize how to apply them to the real field. We introduce a test procedure according to the assumption that CDV accumulation level on ATM network depends on the test traffic´s own characteristics. We also propose new test traffic and, as the measurement using real ATM switches, validate that the proposed test traffic allows more precise results for CDV investigation
