Abstract

This paper uses fault injection to compare the ability of two fault-tolerant software architectures to protect an application from faults. These two architectures are Voltan, which uses process duplication, and Chameleon ARMORs, which use self-checking. The target application is a Dynamic Host Configuration Protocol (DHCP) server, a widely used application for managing IP addresses. NFTAPE, a software-based fault injection environment, is used to inject three classes of faults, namely random memory bit- flip, control-flow, and high-level target specific faults, into each software architecture and into baseline Solaris and Linux versions.
