There are several approaches to analyse the worst-case response times of sporadic packets
transmitted over priority-preemptive wormhole networks. In this paper, we provide an
overview of the different approaches, discuss their strengths and weaknesses, and propose
an approach that captures all effects considered by previous approaches while providing
tight yet safe upper bounds for packet response times. We specifically address the problems
created by buffering and backpressure in wormhole networks, which amplifies the problem …
