Hierarchical Error Detection and Recovery in a Software Implemented Fault Tolerance (SIFT) Environment

A key issue in the design of reliable distributed systems is how to make the entities that provide the reliability properties of the system, themselves failure resilient. An application executing in such a system is dependent on these entities and hence, it is critical to protect not just the application, but also the components of the fault tolerance layer, through a variety of error detection...

An Experimental Evaluation of the REE SIFT Environment for Spaceborne Applications

Few distributed software-implemented fault tolerance (SIFT) environments have been experimentally evaluated using substantial applications to show that they protect both themselves and the applications from errors. This paper presents an experimental evaluation of a SIFT environment used to oversee spaceborne applications as part of the Remote Exploration and Experimentation (REE) program at th...

Measurement-Based Analysis of System Dependability Using Fault Injection and Field Failure Data

The discussion in this paper focuses on the issues involved in analyzing the availability of networked systems using fault injection and the failure data collected by the logging mechanisms built into the system. In particular we address: (1) analysis in the prototype phase using physical fault injection to an actual system. We use example of fault injection-based evaluation of a software-imple...

The FTMPS { Project : Design and Implementation of Fault { Tolerance Techniques for Massively Parallel Systems 1

The FTMPS-project provides a solution to the need for fault{ tolerance in large systems. A complete fault-tolerance approach is developed and being implemented. The built-in hardware error-detection features combined with software error-detection techniques provide a high coverage of transient as well as permanent failures. Combined with the diagnosis software, the necessary information for the...
