Description
Summary:Many Industrial Internet of Things (IIoT) applications have zero fault tolerance. Redundant networks are hence an important prerequisite for a dependable infrastructure to serve the various data traffic classes required for such applications. In this paper, we perform a delay analysis of a Quality Checks After Production (QCAP) application, which is running on a Time-Sensitive Network (TSN). We evaluate the worst-case delay of all data flows traversing the redundant TSN network using a Network Calculus (NC) based framework. We also evaluate how network parameters and configurations affect the QCAP application's service requirements.
