Query: A QoS Aware Approach to Service-Oriented Communication in Future
  Automotive Networks   Service-Oriented Architecture (SOA) is about to enter automotive networks
based on the SOME/IP middleware and an Ethernet high-bandwidth communication
layer. It promises to meet the growing demands on connectivity and flexibility
for software components in modern cars. Largely heterogeneous service
requirements and time-sensitive network functions make Quality-of-Service (QoS)
agreements a vital building block within future automobiles. Existing
middleware solutions, however, do not allow for a dynamic selection of QoS.
  This paper presents a service-oriented middleware for QoS aware communication
in future cars. We contribute a protocol for dynamic QoS negotiation along with
a multi-protocol stack, which supports the different communication classes as
derived from a thorough requirements analysis. We validate the feasibility of
our approach in a case study and evaluate its performance in a simulation model
of a realistic in-car network. Our findings indicate that QoS aware
communication can indeed meet the requirements, while the impact of the service
negotiations and setup times of the network remain acceptable provided the
cross-traffic during negotiations stays below 70% of the available bandwidth.
