In this new scenario, software components are to be added, removed, updated and migrated between computing units. To isolate the software components from each other and allow its orchestration, a container-based virtualization approach is being tested throughout this research. The analysis focuses on the question if this virtualization technology could be an option to ensure an interference-free operation. Four different sample applications from the automotive environment are tested for their susceptibility to resource contention. The research on the one hand shows that CPU and memory used by an application can be largely isolated with this technology, but on the other hand, it becomes apparent that support for I/O-heavy usage is currently not implemented sufficiently for container engines.

This part of the automobile is known as the next generation communication network. Since the new car-systems can be extended by various services at any time, the network must adapt dynamically to new requirements wherever possible. For example, data flow must be configured dynamically between new services. Also data rates will be much higher in the future than today. This is one of the main reasons why we need to search for new technologies for data transfer in vehicles. This is based on an in-vehicle ethernet network. The process of configuring networks automatically has been discussed several times in recent years. One of the next steps is verifying and validating the automatic configuration process during the development of the new communication network. This research paper identifies several ways to ensure the automatically generated network configuration leads to a secure system. To achieve that, other parts of the company’s enterprise IT architecture and network technologies, the conventional vehicle network and other options for verification and validation are analysed KW - Automotive KW - Ethernet KW - In-car KW - Vehicle Communications KW - Car-to-Car KW - Autonomous Driving KW - Vehicle Networks Y1 - 2019 SN - 978-989-758-385-8 U6 - https://doi.org/10.5220/0008191601210127 SP - 121 EP - 127 PB - SCITEPRESS - Science and Technology Publications ER -
