Abstract

Although component-based software development has widespread acceptance in the enterprise business and desktop application domains, developers of distributed real-time and embedded (DRE) systems have encountered limitations with the available component middleware platforms, such as the CORBA Component Model (CCM) and the Java 2 Enterprise Edition (J2EE). These limitations often preclude developers of DRE systems from fully exploiting the benefits of component software. In particular, component middleware platforms lack standards-based publisher/subscriber communication mechanisms that support key quality-of-service (QoS) requirements, such as low latency, bounded jitter, and end-to-end operation priority propagation. QoS-enabled publisher/subscriber services are available in object middleware platforms, such as Real-time CORBA, but such services have not been integrated into component middleware due to a number of development and configuration challenges.This paper provides three contributions to the integration of publisher/subscriber services in component middleware. First, we outline key challenges associated with integrating publisher/subscriber services into component middleware. Second, we describe a methodology for resolving these challenges based on software patterns. Third, we describe a pattern-oriented component middleware platform that we have developed to integrate publisher/subscriber services into component middleware applications.
