Current in-vehicle networks are featured by multiple different communication systems. The different automotive network technologies are highly optimized for their special purpose. Since their application domains have very differing requirements, communication across network boundaries is not straight forward and especially upgrading new functionality into already existing vehicle systems is very difficult. This paper presents the architecture and implementation of a communication system that enables the use of very different network technologies over a simple and common API. With this prototype implementation it will be shown that it is able to overcome heterogeneity of different types. The layered architecture enables the transparent use of different networks while the ASN.1 based transport encoding ensures that messages can be interpreted on different nodes running different operating systems and clients written in different programming languages. Bridging different network technologies has been shown by connecting a TCP network with a Bluetooth domain. The benchmark results are satisfactory since this was a proof of concept implementation and there has been no optimization yet. For the future it follows the implementation of transport adapters for automotive networks like CAN and MOST. The authors are going to include the messaging middleware into embedded devices and address the subject of network redundancy and better QoS modeling and real-time capabilities.
