Domain-specific modeling languages for configuring and evaluating enterprise DRE system quality of service

Abstract

The quality of service (QoS) of enterprise distributed real-time and embedded (DRE) systems can degrade under certain operating conditions and system architectures. This paper provides two contributions to research on model-driven development (MDD) tools and methods that help identify and rectify these QoS problems in component-based enterprise DRE systems. First, we show how MDD tools can be used to simplify and automate the evaluation of component-based DRE systems to identify QoS problems. Second, we show how MDD tools can be used to specify alternative QoS polices for component-based DRE systems and synthesize metadata automatically to simplify system (re)configurations that rectify QoS problems. We illustrate our MDD tools on a case study of multi-layer resource management services for shipboard computing systems that automate many aspects of power, navigation, command and control, and tactical operations.
