The Delta-4 approach to dependability in open distributed computing systems

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. The system is used to demonstrate the various fault-tolerance techniques by a replicated database application.<
