Abstract
Data processing systems, each belonging to one of a number of program groups, are connected to a network. Each group includes a data processing system containing a sequencer which determines the sequence of messages transferred over the network. The sequencer of each data processing system is either in the “operation mode” or in the “standby mode.” A sequencer in the standby mode declares the operation mode independently of other sequencers and sends this operation mode declaration to the sequencers of the other data processing systems. When the operation mode declaration is sent a number of times equal to a specified count, the sequencer becomes the operation mode sequencer. When the operation mode sequencer stops, some other standby mode sequencer takes over the function of the operation mode sequencer, thus maintaining consistency in the sequence of messages to be sent to a plurality of data processing systems connected to the network.
