NFTAPE: networked fault tolerance and performance evaluator

Abstract

The NFTAPE is a software implemented, highly flexible fault injection environment for conducting automated fault/error injection-based dependability characterization. NFTAPE: (1) enables a user: (i) to specify a fault/error injection plan, (ii) to carry out injection experiments, and (iii) to collect the experimental results for analysis; (2) targets assessment of a broad set of dependability metrics, e.g., availability, reliability, coverage; (3) operates in a distributed environment; (4) can be configured to implement a variety of fault/error injection strategies and thus to serve multiple users and target systems; (5) imposes minimal disturbance of target systems.
