Abstract
The method carrying out permanent redundant transmission of data messages in disjunctive paths, such that circulating data messages can be reliably identified and destroyed. The method includes splitting a redundant message into two data messages in the respective branching point in a transparent manner. The method further includes causing no additional load for the receiver of the two identical messages by, for instance, allocating a current cycle number to the received data message in a cyclic communication system (). This can also be ensured in a non-cyclic communication system by means of software processing, for instance, by processing the header identifier of the data messages. In particular, the behavior of the communication system () with respect to 'learning' the addresses in the individual users (), more particularly the switches, is not altered for the remaining non-redundant data traffic.
