In-Vehicle Networks (IVN) are under intense pressure to be both resource efficient at low cost and flexible enough for the future. The deployment of a large number of new sensors for autonomous driving and self-awareness significantly increases the demand for network resources. In addition, statically designed networks lack flexibility or have large over-provisioning of resources due to the dynamics of network traffic. Application-aware resource management addresses both of these issues. It allows the network to be reconfigured while controlling application requirements, increasing resource utilization, and providing flexibility for future demands. Our timestamp-based reconfiguration protocol ensures fast, lossless reconfiguration of high bandwidth data connections. Based on global time synchronization, it enables precise reconfiguration without increasing the risk of data loss and reduces the risk of inconsistent network configurations by exploiting the object slack created by large object transfers consisting of hundreds of individual packets. Using software-based Linux switches as the network, we demonstrate the use of the reconfiguration protocol under real-world conditions.

With the current trend towards large data volumes, state-of-the-art communication and data management solutions based on the publish/subscribe pattern reach the network limits, hampering the deployment of advanced edge and cloud computing services. A main reason is the established publisher-centric distribution mechanism that over-utilizes network resources. We suggest a network and subscriber-centric adaptive data caching communication scheme supported by dynamic network management and configuration, which has great potential to solve the data distribution challenges. We show that state-of-the-art publish/subscribe middlewares like Data Distribution Service (DDS) can transparently be combined with such software caching.

This paper summarizes the talks of a special session on the IPF 2.0 project, a collaborative German-US research project that leverages self-awareness principles for the self-management of distributed systems of autonomous multiprocessor systems-on-chip (MPSoCs).

The current roadmaps and surveys for future wireless networking typically focus on communication and networking technologies and use representative applications to derive future network requirements. Such a benchmarking approach, however, does not cover the application integration challenge that arises from the many distributed applications sharing a network infrastructure, each with their individual topology and data structure. The paper addresses V2X networks as an important example. Crucial end-to-end application constraints including real-time and safety encourage a closer look at application interference and systematic integration. This perspective paper proposes a two-layer resource management that divides the problem into an application integration and a network management task. Valet parking with high-resolution infrastructure camera support is elaborated as a use case that overarches vehicle network and wireless network management. Experiments demonstrate the benefits of complementing the current network-centric management by an application-centric integration.
