This paper discusses measures to make a distributed system based on the Time-Triggered Architecture resistant to arbitrary node failures. To achieve this, the presented approach introduces a central guardian as part of the interconnection network. This guardian acts as a supervising unit to node computers by checking for fault hypothesis compliance at their respective network interfaces. By implementing appropriate algorithms the guardian is able to transform failure modes of nodes that cannot be tolerated by the fault hypothesis of the TTP/C protocol. At the interface to correct nodes even an arbitrarily faulty node will then be compliant to the fault hypothesis of the TTP/C communications protocol.
