About this title

Synopsis:

Delta-4 is a 5-nation, 13-partner project that has been investigating the achievement of dependability in open distributed systems, including real-time systems. This book describes the design and validation of the distributed fault-tolerant architecture developed within this project. The key features of the Delta-4 architecture are: (a) a distributed object-oriented application support environment; (b) built-in support for user-transparent fault­ tolerance; (c) use of multicast or group communication protocols; and (d) use of standard off­ the-shelf processors and standard local area network technology with minimum specialized hardware. The book is organized as follows: The first 3 chapters give an overview of the architecture's objectives and of the architecture itself, and compare the proposed solutions with other approaches. Chapters 4 to 12 give a more detailed insight into the Delta-4 architectural concepts. Chapters 4 and 5 are devoted to providing a firm set of general concepts and terminology regarding dependable and real-time computing. Chapter 6 is centred on fault-tolerance techniques based on distribution. The description of the architecture itself commences with a description of the Delta-4 application support environment (Deltase) in chapter 7. Two variants of the architecture - the Delta-4 Open System Architecture (OSA) and the Delta-4 Extra Performance Architecture (XPA) - are described respectively in chapters 8 and 9. Both variants of the architecture have a common underlying basis for dependable multicasting, i. e.

Synopsis:

This book describes the design philosophy and concepts of a novel distributed fault-tolerant architecture developed by the Delta-4 project, a five-nation, thirteen-partner project investigating the achievement of dependability in open distributed systems, including real-time systems. The architecture features a dependable communication system using standard local area network technology, a distributed object-oriented application support environment, use of multicast or group communication protocols, and built-in support for user-transparent fault-tolerance. The book opens with an overview of the architecture and its objectives, then describes the concepts of dependability, real-time and distributed fault-tolerance and the design of each of the major architectural components, including the Delta-4 applications support environment and the open and extra performance variants of the architecture. Work is described in the field of security, on intrusion-tolerance and tolerance of software design faults by diversified design. Finally, there is an overview of the validation activities carried out on the architecture.
