dc.description.abstractEthernet was not originally designed for real-time communication. However, the growing need for available bandwidth combined with the fact that it is an open standard has made the automotive industry to consider it as a possible solution for in-vehicle communication. To enable Ethernet to be used in real-time communication, certain guarantees (i.e. end-to-end delay bounds) have to be provided. The purpose of this thesis is to propose a network architecture for in-vehicle communication and to develop a technique for analysis of end-to-end delay. In order to meet this objective, both theoretical and experimental methods were deployed. A theoretical model of the system under consideration was produced, based on network calculus. An experimental setup, which accurately reflected an automotive communication network, was implemented in order to evaluate the theoretical model. Three use cases were investigated for two different maximum transmission units. The results obtained by the experiments provided valuable feedback that redefined the analytical model. Although the end-to-end delay bounds proved to be higher than originally anticipated, the validity of the theoretical model was confirmed for the great majority of the experiments. As a conclusion, it was shown that Ethernet can be used as a backbone in a domain-oriented architecture as long as support for IEEE 802.1Q and 802.1p is provided both in hardware and software. Given the fact that future versions of AUTOSAR will support these standards and that implementation of such a system can be done with commercial of-the-shelf equipment, great potential is being presented for the designers of future vehicular communication networks.
