Experiment illustrating Failure Acceleration and Error Propagation in Fault - Injection
نویسندگان
چکیده
A system level fault injection experiment measuring changes in probability of failure and error propagation as a function of failure acceleration. It demonstrates that: (1) Probability of failure increases with failure acceleration, and (2) Error propagation decreases with failure acceleration .

Evaluation of Fault Handling of the Time-Triggered Architecture with Bus and Star Topology
Arbitrary faults of a single node in a time-triggered architecture (TTA) bus topology system may cause error propagation to correct nodes and may lead to inconsistent system states. This has been observed in validation work using software implemented fault injection (SWIFI) and heavy-ion fault injection techniques in a TTA cluster. In a TTA system, the membership and the clique avoidance algori...
متن کاملError Propagation Analysis of Software Architecture Specifications
As software architecture is becoming an important asset in the development of software systems, the study of quantitative assessment of software architectures is gaining importance due to its role in assessing their quality. Error propagation between software system components is a quantitative factor that reflects on the reliability of a software product. We introduce a framework for experimen...
متن کاملAn experimental comparison of fault and error injection
The complex interactions between faults, errors, failures and fault handling mechanisms can be studied via injection experiments. This paper presents an investigation of both fault and error injection techniques for emulating software faults. For evaluation, 1600 software faults and 5400 time-triggered errors were injected into an embedded real-time system. The cost-related results are: (i) the...
متن کاملEvaluation of Babbling Idiot Failures in Flexray-based Networkes
This paper evaluates the error propagation and its effects in babbling idiot failure in a FlexRay-based network. The evaluation is based on about 35680 bit-flip fault injections inside different parts of the FlexRay communication controller. To do this, a FlexRay communication controller is modeled by Verilog HDL at the behavioral level. Then, this controller is exploited to setup a FlexRay-bas...
متن کاملAutomated Monitor Based Diagnosis in Distributed Systems
In today's world where distributed systems form many of our critical infrastructures, dependability outages are becoming increasingly common. In many situations, it is necessary to not just detect a failure, but also to diagnose the failure, i.e., to identify the source of the failure. Diagnosis is challenging since high throughput applications with frequent interactions between the different c...
