A method is described for ordering a plurality of messages from a plurality of sources wherein, in order for all the application processes to receive the messages in the same order, a single relay process common to all the sources is selected from the application processes, the other application processes constituting slave processes. All messages broadcast by the sources are rebroadcast from the relay process to all the application processes, including the relay process. The relay process processes data from all messages that it rebroadcasts. The slave process processes only data from messages received via the relay process, data from messages received directly from the sources not being processed. Applications include data processing systems, in particular where part of the software is replicated.
