This paper proposes and evaluates error detection and recovery mechanisms suitable for embedded systems. The purpose of these mechanisms is to provide detection of and recovery from data errors in internal variables. A classification scheme for variables enables us to construct a parameterised detection and recovery mechanism for each variable. Error detection is handled by executable assertion...

Julep is an object-oriented testbed designed for implementation and analysis of process recovery protocols. It is written in Java, and runs as a layer underneath a Java-based distributed application. Only minor modifications to a typical distributed application are necessary to use Julep as a communication mechanism. Julep is designed to allow new process recovery mechanisms to be quickly incor...
