Blocking Analysis of Time-Driven Switching

This paper presents a complete closed-form timedomain analysis of the blocking probability of time-driven switching (TDS) for the single node case. In this work blocking is defined as the occurrence in which transmission resources are available in both inlet and outlet, but there is no schedule. The main constraints for finding a schedule are: (i) the load and (ii) the maximum scheduling delay between inlet availability and outlet availability. As the maximum scheduling delay (buffering) increases the blocking probability is reduced. The outcome of the analysis in this paper is the exact blocking probabilities for all possible maximum scheduling delays, under all load conditions.
