This article presents an approach for deriving upper bound for end-to-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 accu-rately reflects an automotive communication network, was implemented in or-der to evaluate the theoretical model. The results obtained by the experiments provided valuable feedback that redefined the analytical model.
