Cyber-Physical Systems (CPSs) usually execute critical applications, which imposed the use of specialised networks due to their high reliability and hard real-time requirements. There is a growing interest in developing CPSs capable of adapting to unpredictable changes in the environment without jeopardising their correct operation. Ethernet is an appealing technology to build the networks of future adaptive CPSs, due to the advantages in bandwidth, cost and internet compatibility offered. Ethernet lacks real-time, reliability and flexibility services. Thus, the IEEE Time-Sensitive Networking task group are developing a set of standards (commonly referred to as TSN) to provide Ethernet with said services. Nevertheless, TSN’s reliability services are not enough for some highly-critical applications. Thus, we proposed a mechanism to tolerate temporary faults in the Layer 2 of TSN-based networks. In this work we propose to mix time and spatial redundancy over a TSN-based network to increase its reliability while reducing resource consumption.
