Abstract

The paper presents a set of experiments on real time protocols using the ORCHESTRA software fault injection environment. The paper first describes a specific implementation of ORCHESTRA for testing applications that use Unix sockets for communication. A novel feature of this tool is that it utilizes operating system support provided by Real Time Mach to quantify and compensate for the intrusiveness of the fault injection mechanism. The fault injection experiments which are described, tested fault tolerance and timing behavior of two target real time protocols. In addition, timing intrusiveness of ORCHESTRA was measured during the course of these experiments
