The structures for the expression of fault-tolerance provisions into the application software are the central topic of this paper. Structuring techniques answer the questions \How to incorporate fault-tolerance in the application layer of a computer program" and \How to manage the faulttolerance code". As such, they provide means to control complexity, the latter being a relevant factor for the...

An important objective of software fault tolerant systems should be to provide a fault-tolerance infrastructure in a manner that minimizes the effort required by the application developer. In the limit, the objective is to provide fault tolerance transparently to

Service-oriented systems are usually composed by heterogeneous Web services, which are distributed across the Internet and provided by organizations. Building highly reliable service-oriented systems is a challenge due to the highly dynamic nature of Web services. In this paper, the authors apply software fault tolerance techniques for Web services, where the component failures are handled by f...

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...

The forbidden faulty set analysis of restricted connectivity and fault tolerance assumes that a set of nodes cannot be fau...

In computational Grid, fault tolerance is an imperative issue to be considered during job scheduling. Due to the widespread use of resources, systems are highly prone to errors and failures. Hence fault tolerance plays a key role in grid to avoid the problem of unreliability. The two main techniques for implementing fault tolerance in grid environment are check pointing and replication. Grid Co...

The growing complexity of safety-critical embedded systems is leading to an increased complexity of safety analysis models. Often used fault tolerance mechanisms have complex failure behavior and produce overhead compared to systems without such mechanisms. The question arises whether the overhead for fault tolerance is acceptable for the increased safety of a system. In this paper, an approach...

Fault tolerance is an important aspect in realtime computing. In real-time systems, tasks could be faulty due to various causes. Faulty tasks may compromise the safety and performance of the whole system and even cause disastrous consequences. In this paper, we study the possibilities of applying feedback control of software execution to real-time systems for fault tolerance purposes. A new fau...

In this paper, we study the problem of synthesizing faulttolerant components from specifications, i.e., the problem of automatically constructing a fault-tolerant component implementation from a logical specification of the component, and the system’s required level of fault-tolerance. We study a specific level of fault-tolerance: masking tolerance. A system exhibits masking tolerance when both...

As fault tolerance is the ability of a system to perform its function correctly even in the presence of faults. Therefore, different fault tolerance techniques are critical for improving the efficient utilization of expensive resources in high performance data grid systems. One of the most popular strategies of fault tolerance is the replication, it creates multiple copies of resources in the s...
