A Delayed Vacation Model of an M/G/1 Queue with Setup Time and Its Application to SVCC-Based ATM Networks (Special Issue on Telecommunications Network Planning and Design)

SUMMARY The emerging ATM network will support permanent , semi-permanent and switched virtual channel connections (SVCC). A number of simulation studies have been carried out to study the performance of SVCCs using empirical data. The absence of an analytical model has prevented the study of SVCCs under known traac distributions. In this paper, we develop a new delayed vacation model to facilitate the performance study of SVCCs with conngurable inactivity timer in the ATM network interfacecard (NIC). Comparisonwith simulationresults indicates that the proposed model is very accurate and can be effectively used to optimise the performance of SVCCs by selecting an appropriate inactivity timer.
