The Design and Performance of Configurable Component Middleware for Distributed Real-Time and Embedded Systems

Overview

This paper makes three contributions to research on QoS-enabled component middleware for DRE systems in the context of the Component-Integrated ACE ORB (CIAO). First, it describes the design of CIAO's static component configuration mechanisms, which enhance configurability by avoiding features that are not supported by key real-time platforms, while reducing run-time overhead and footprint. Second, it compares the performance of dynamic and static configuration mechanisms in CIAO to help guide the selection of suitable configuration mechanisms based on specific requirements of each DRE system. Third, it presents an empirical comparison of CIAO's static configuration mechanisms to the static configuration mechanisms in Boeing's PRISM avionics component middleware solution.
