Available in PDF, EPUB and Kindle. Book excerpt: Real-time computer systems are very often subject to dependability requirements because of their application areas. Fly-by-wire airplane control systems, control of power plants, industrial process control systems and others are required to continue their function despite faults. Fault-tolerance and real-time requirements thus constitute a kind of natural combination in process control applications. Systematic fault-tolerance is based on redundancy, which is used to mask failures of individual components. The problem of replica determinism is thereby to ensure that replicated components show consistent behavior in the absence of faults. It might seem trivial that, given an identical sequence of inputs, replicated computer systems will produce consistent outputs. Unfortunately, this is not the case. The problem of replica non-determinism and the presentation of its possible solutions is the subject of Fault-Tolerant Real-Time Systems: The Problem of Replica Determinism. The field of automotive electronics is an important application area of fault-tolerant real-time systems. Systems like anti-lock braking, engine control, active suspension or vehicle dynamics control have demanding real-time and fault-tolerance requirements. These requirements have to be met even in the presence of very limited resources since cost is extremely important. Because of its interesting properties Fault-Tolerant Real-Time Systems gives an introduction to the application area of automotive electronics. The requirements of automotive electronics are a topic of discussion in the remainder of this work and are used as a benchmark to evaluate solutions to the problem of replica determinism.

Book excerpt: Our main objective in this MURI project has been to investigate foundational and experimental techniques tor enabling real-time, fault-tolerant network protocols. Our overall research goal has been to study networking architectures, services, and algorithms which require innovative quality-of-service and fault-tolerance mechanisms. We have focused on multimedia delivery in traditional client-server architectures, both in the case of the Internet and wireless networks, as well as on peer-to-peer content delivery and on mobile ad-hoc networks. The unique composition of the team has brought new synergies to the problem domain which permits the complete illumination of each newly proposed protocol from all angles, from mathematical modeling and analysis to experimental evaluation, from real-time and QoS aspects to fault-tolerance and reliability aspects. Our approach is to improve newly designed protocols through feedback from timing and fault analysis, and to develop new analysis techniques driven by new protocol designs.

Download or read book Formal Techniques in Real Time and Fault Tolerant Systems written by Jan Vytopil and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formal Techniques in Real-Time and Fault-Tolerant Systems focuses on the state of the art in formal specification, development and verification of fault-tolerant computing systems. The term `fault-tolerance' refers to a system having properties which enable it to deliver its specified function despite (certain) faults of its subsystem. Fault-tolerance is achieved by adding extra hardware and/or software which corrects the effects of faults. In this sense, a system can be called fault-tolerant if it can be proved that the resulting (extended) system under some model of reliability meets the reliability requirements. The main theme of Formal Techniques in Real-Time and Fault-Tolerant Systems can be formulated as follows: how do the specification, development and verification of conventional and fault-tolerant systems differ? How do the notations, methodology and tools used in design and development of fault-tolerant and conventional systems differ? Formal Techniques in Real-Time and Fault-Tolerant Systems is divided into two parts. The chapters in Part One set the stage for what follows by defining the basic notions and practices of the field of design and specification of fault-tolerant systems. The chapters in Part Two represent the `how-to' section, containing examples of the use of formal methods in specification and development of fault-tolerant systems. The book serves as an excellent reference for researchers in both academia and industry, and may be used as a text for advanced courses on the subject.

This book was released on 2013-04-17 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of computer systems to be embedded in critical real-time applications is a complex task. Such systems must not only guarantee to meet hard real-time deadlines imposed by their physical environment, they must guarantee to do so dependably, despite both physical faults (in hardware) and design faults (in hardware or software). A fault-tolerance approach is mandatory for these guarantees to be commensurate with the safety and reliability requirements of many life- and mission-critical applications. This book explains the motivations and the results of a collaborative project', whose objective was to significantly decrease the lifecycle costs of such fault tolerant systems. The end-user companies participating in this project already deploy fault-tolerant systems in critical railway, space and nuclear-propulsion applications. However, these are proprietary systems whose architectures have been tailored to meet domain-specific requirements. This has led to very costly, inflexible, and often hardware-intensive solutions that, by the time they are developed, validated and certified for use in the field, can already be out-of-date in terms of their underlying hardware and software technology.

Download or read book Real time Fault tolerant Communication in Computer Networks written by Qin Zheng and published by . This book was released on 1993 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "A network is required to provide the users with a convenient means of guaranteeing delay bounds in message transmission and making message transmission tolerant of network component failures. Solutions to this problem will greatly improve the quality of service of the contemporary computer networks and expand their application domains to such areas as distributed real-time controls and digital continuous-media (motion video, audio) transmissions. Our solution to the problem is to use a new transfer mode called a real-time channel which guarantees the timely delivery of messages like the circuit-switched transmission while preserving the high transmission efficiency of the packet-switched mode. We give a comprehensive coverage of this new transfer mode, from the fundamental deadline scheduling theory and real-time channel protocols, to the detailed hardware implementation. Using the spatial redundancy of a network topology, real-time fault-tolerant communication is achieved by enhancing the basic real-time channels to be Single Failure Immune (SFI) or Isolated Failure Immune (IFI). Backup channels can also be used to increase the reliability of real-time channels. The issue of establishing real-time channels over shared-medium Local Area Networks (LANs) is then discussed, which is of practical importance since most end systems are connected to a LAN first and then to a point-to-point Wide Area Network (WAN). We also present a technique which can significantly improve the FDDI's capacity of supporting real-time traffic with a few simple modifications to its Medium Access Control (MAC) protocols. Finally, the application of our results for multimedia networking is illustrated through simulations."

Available in PDF, EPUB and Kindle. Book excerpt: The increasing use of embedded networks in safety-critical systems, for example in the automotive and avionics fields, comes with additional requirements like real-time capabilities and fault-tolerance. This work presents the new fault-tolerant real-time protocol TEA, which provides the ability of fault-tolerant dynamic arbitration, in opposite to already present protocols. TEA tolerates single- and double faults. This is implemented using a time-triggered method. Therefore, a special hardware architecture is presented, where two nodes are guarding each other. The arbitration takes place in cycles, which are separated into a regular and an extension part. Every controller in the network can send in the extension part, if it sends a request in the the regular part of the cycle. A fault-tolerant agreement protocol decides, if the controller gets permission to send or not. In order to formalize this approach, two new methods will be presented, to model the fault propagation and the temporal behavior of a system. Using this methods, the behavior of a TEA-network is analyzed. Furthermore, it will be shown how a more dynamic use of the extension part can be accomplished, by determining the time to send for a controller by the message length which can be variable. Furthermore, a scheduling algorithm for the extension part is presented, which can be easily adapted to different scheduling strategies.
