V.T. Nguyen, R. Lo Cigno, Y. Ofek, "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.
