Service-Oriented Architecture (SOA) is about to enter automotive networks\nbased on the SOME/IP middleware and an Ethernet high-bandwidth communication\nlayer. It promises to meet the growing demands on connectivity and flexibility\nfor software components in modern cars. Largely heterogeneous service\nrequirements and time-sensitive network functions make Quality-of-Service (QoS)\nagreements a vital building block within future automobiles. Existing\nmiddleware solutions, however, do not allow for a dynamic selection of QoS.\n This paper presents a service-oriented middleware for QoS aware communication\nin future cars. We contribute a protocol for dynamic QoS negotiation along with\na multi-protocol stack, which supports the different communication classes as\nderived from a thorough requirements analysis. We validate the feasibility of\nour approach in a case study and evaluate its performance in a simulation model\nof a realistic in-car network. Our findings indicate that QoS aware\ncommunication can indeed meet the requirements, while the impact of the service\nnegotiations and setup times of the network remain acceptable provided the\ncross-traffic during negotiations stays below 70% of the available bandwidth.\n
