Towards Time-Sensitive Networking in Heterogeneous Platforms with Virtualization

The advent of commercial-off-the-shelf (COTS) heterogeneous multicore platforms is offering many opportunities in the market of embedded computing systems for many application scenarios. The integration of multiple computing elements in a single device entails impressive performance capabilities. At the same time, the increased complexity of emerging systems requires the integration of more subsystems and functionalities, among others the communication subsystem. This work deals with the desirable properties of software transmission mechanisms to enable TSN communications in heterogeneous platforms handled by a hypervisor. Moreover, preliminary simulation results provide some insights on the limits and the advantages of the investigated architectures.
