Experimental evaluation of end-to-end delay in switched Ethernet application in the automotive domain

This article presents an approach for deriving upper bound for endto-end delay in a double star switched Ethernet network. Four traffic classes, following a strict priority queuing policy, were considered. The theoretical analysis was based on network calculus. An experimental setup, which accurately reflects an automotive communication network, was implemented in order to evaluate the theoretical model. The results obtained by the experiments provided valuable feedback that redefined the analytical model.
