Abstract
A data processing system comprises a number of processing nodes interconnected by a data transmission network. The network is 'hairpin' shaped, having a first leg, a second leg, and a loopback connection connecting the first leg to the second leg. Each node sends public write messages on to the first leg, and receives messages from the second leg. All the messages flow through the loopback connection, which thus serves as a central chronology point for the system, defining a unique chronological order for the messages. The network can be reconfigured, to split it into a number of sub-networks, each with first and second legs interconnected by a loopback connection. The system may include a backup node, for disaster recovery, situated at a very long distance from the processing nodes.
