In this paper, we present some of the fault tolerance management mechanisms being implemented in the Multi-μ architecture, namely its support for replica non-determinism. In this architecture, fault tolerance is achieved by node active replication, with software based replica management and fault tolerance transparent algorithms. A software layer implemented between the application and the real...

This paper presents a fault detection, isolation and reconstruction (FDIR) mechanism for the fault-tolerant system. A self-detection component is introduced to the normal dual-channel redundant system, and the component can detect the outputs of the behavior model and the nominal system model. The control strategy is reconfigured by using the differences between the outputs of the behavior mode...

Management of large-scale parallel and distributed applications is an extremely complex task due to factors such as centralized management architectures, lack of coordination and compatibility among heterogeneous network management systems, and dynamic characteristics of networks and application bandwidth requirements. The development of an integrated network management framework that is proact...

Abstract— An important aspect of network management is fault management, i.e., determining, locating, isolating, and correcting faults in the network. We study modeling of communication network protocols, and their fault detection, fault identification and fault location in the discrete event systems diagnosis framework. Our approach provides a systematic way of performing fault diagnosis in ne...

Transformation equipment conditional monitoring technology is the key technology of intelligent substation construction, and it is also one of the core content of intelligent substation construction. Guangxi power grid has constructed a sensor network based variable and integrated electrical equipment on-line monitoring and evaluation platform. In the platform, through the equipment fault diagn...

T paper presents a project management policy in which the appearance of software faults during system construction is used to determine the timing of system integration activities (e.g., team meetings, analyzing modules for interface inconsistencies, system fault correction, and so on). System integration is performed only if a threshold fault count has been exceeded; otherwise, module developm...

Fault diagnosis has attracted extensive attention for its importance in the exceedingly fault management framework for cloud virtualization, despite the fact that fault diagnosis becomes more difficult due to the increasing scalability and complexity in a heterogeneous environment for a virtualization technique. Most existing fault diagnoses methods are based on active probing techniques which ...

The high-performance, scalability and miniaturization requirements together with the power, mass and cost constraints mandate the use of commercial-off-the-shelf (COTS) components and standards in the X2000 avionics system architecture for deep-space missions. In this paper, we report our experiences and findings on the design of an IEEE 1394 compliant fault-tolerant COTS-based bus architecture...

Graceful degradation entails a proportional loss of functionality or the reduction in the quality of services a system provides in response to faults. Compared to traditional techniques, graceful degradation is a promising approach to achieving fault tolerance at reduced cost. Current research using this approach in distributed embedded systems assumes a central management unit responsible for ...
