Middleware for Resource-Aware Deployment and Configuration of Fault-Tolerant Real-Time Systems

Developing large-scale Distributed Real-time and Embedded (DRE) systems is hard in part due to complex deployment and configuration issues involved in satisfying multiple Quality for Service (QoS) properties, such as real-timeliness and fault tolerance. This paper makes three contributions to the study of deployment and configuration middleware for DRE systems that satisfy multiple QoS properties. First, it describes a novel task allocation algorithm for passively replicated DRE systems to meet their real-time and fault-tolerance QoS properties while consuming significantly less resources.
