A method of transmitting data between a set of data processing nodes interconnected by a communications network. Each node broadcasts data to the other nodes by causing a train of such data to travel over the network around a looped circuit or "ring" passing through each of said nodes, each node in the ring having a predecessor and a successor. A counter is provided in the data train, and on receiving a data train sent by its predecessor, each node recovers the counter from the received data train, increments the counter, and dispatches to its successor a new data train including the counter as incremented. It also stores the new data train with the incremented counter in its memory so that it is possible to implement a simple fault recovery procedure in the event of one of the nodes becoming faulty.
