Aims

The aim of the Delta-4 project was to provide a computational and communication infrastructure for application domains that require distributed system solutions with various dependability and real-time constraints. The scale of distribution in the targeted application domains is commensurate with the distances that can be covered by local area networks.

Achievements

The Delta-4 project, which ran for 5 years (1986-91) with around 40 Mio Euro funding, is considered one of the most relevant European projects to date, having launched seminal research in fault tolerance in open distributed computing, using modular COTS systems, a pioneering achievement that left an indelible mark in the way F/T systems are designed today.

A seminal publication in the fault tolerance flagship conference FTCS (nowadays DSN):

has introduced the main features of DELTA-4: the innovative architecture, dependability model and implementation approaches. The paper introduced many concepts and laid down fundamental advancements in the theory and practice of fault-tolerant computing, which are now commonly used in many current dependable systems. It inspired further seminal research inside the project consortium itself, as well as inspiring many researchers and practitioners.

A brief summary of the s.o.t.a. advances reported in the paper can be found in the Delta-4 press release.

A full account of the results of Delta-4 was cast in book in 1991, and is made available below, provided the users respect the copyright notice in http://www.navigators.di.fc.ul.pt/wiki/Publications.
