Abstract
The invention relates to a method for providing a fault-tolerant global time and for the fault-tolerant transport of time-controlled messages in a distributed real-time computer system which comprises external computers and a fault-tolerant message distribution unit, FTMDU. The FTMDU comprises at least four components which supply the global time to the external computers by means of periodic external synchronization messages, wherein the external computers each set their local clock to the received global time, wherein each external sender of a time-controlled message transmits two message copies of the message to be sent via two different communication channels to two different components of the FTMDU at periodic sending times defined a priori in timetables, wherein these two message copies are delivered within the FTMDU via two independent communication paths to those two components of the FTMDU which are connected to an external receiver of the message via communication channels.
