The design of an extra performance architecture for Delta-4, which explicitly supports the requirements of real-time systems with respect to throughput and response, is presented. The Delta-4 approach to fault tolerance is based on the replication of software components on distinct host computers using a range of different replication strategies. The problems of replicate divergence are discussed, and a solution based on message selection and preemption synchronization messages is proposed. A de...

As part of the European Strategic Programme for Research in Information Technology (ESPRIT), the Delta-4 project is seeking to define an open, fault-tolerant, distributed computing architecture. The authors present the overall Delta-4 framework for open, fault-tolerant, distributed computing systems and sketch the current implementation, which is based on a local area network with specific atomic multicasting and error-processing protocols for communicating between replicated software components...
