Work in Progress: Efficient TSN network interface handling in a mixed-criticality system

Multicore processor architectures facilitate the integration of applications with different real-time and security requirements. We propose a mixed-criticality system relying on hardware-assisted virtualization that not only shares CPU and memory resources, but also an Ethernet Time-Sensitive Networking (TSN) interface, between applications, taking into account their Quality of Service (QoS) and security requirements. This paper shows how TSN network features can be efficiently exploited in industrial and automotive mixed-criticality systems.
