During the last decades, the complexity in automotive communication media increased sharply. A solution to this problem might be a network based approach with a simple physical layer, which provides the necessary features like fault tolerance through its architecture. In this paper a network based approach to automotive communication media is analyzed with a focus on timing issues. Using queuing theory it is shown that a well designed system with this approach can fulfil the timing criteria of safety relevant automotive applications to a satisfactory degree. In this paper has provided an overview of a network approach to safety relevant communication for automotive electronics as well as a more detailed analysis of the timing behavior. Using queuing theory it was shown that it is possible for such an approach to have a maximum time required for message delivery which is comparable to FlexRay and a time for error detection, which is comparable to CAN in an X-by-wire environment. With issues like implementation of the FEC solved, it is believed that the network approach can be a promising alternative to existing communication systems.
