Mission-critical systems (MCSs) have embraced new design paradigms such as service-oriented architecture (SOA) and IEEE 802.1 Time-sensitive Networking (TSN). These approaches tackle the static and closed-loop design and configuration of MCSs to address their strict performance and resilience requirements. While SOA enables the dynamic placement of critical services over virtualized hardware, TSN provides several protocols to establish deterministic communication over standard Ethernet equipment. This paper presents a prototype combining SOA and TSN to design flexible and fault-tolerant MCSs. It demonstrates the benefits of dynamic service migration and time-sensitive redundancy protocols to increase the resilience of MCSs against node and link failures, respectively. Moreover, it presents additional advanced functionalities like optimal service distribution and security monitoring for new TSN protocols.
