Delay analysis of space division output buffered multichannel switches

In this article we continue the analysis of a space division output buffered multichannel switch operating in an ATM environment. The switch is modeled as a discrete time, batch arrival, multiserver queuing system, with infinite buffer and geometric service time. Many system measurements are analyzed. Expressions for the Probability Generating Functions (PGFs) of unfinished work, queuing time, and waiting time are obtained and expectations for the corresponding random variables are derived. Many numerical examples are presented to prove the obtained results.
