....consequences of such a failure will influence the operation of at most 1 node. We call such a device a guardian. Actually, there must be at least 2 guardians to cope with the faults of the single fault hypothesis. Moreover, a correct guardian must not be able to produce correct frames on its own [12, 1]. node 1 node 2 node 3 communication medium guardian 1 guardian 0 Figure 3. System of 4 nodes with replicated channels and guardians The task of the guardian is to prevent a malicious node from sending outside its slot, which prevents a failure in the time domain. We assume that the ....

....of the fault hypothesis (fail silent nodes in TTAbus) and can bring the application into the safe state in case the fault hypothesis is violated. However, for fail operational applications, the TTA star interconnection that tolerates arbitrary (i.e. Byzantine) node faults is recommended [42] [43]. In the TTA star configuration, the guardians are integrated into two replicated central star couplers as depicted in Figure 6. This has the following advantages: The guardians are fully independent and located at a physical distance from the nodes they protect. In a cluster comprising n ....
