Abstract

Distributed real-time and embedded (DRE) applications possess stringent quality of service (QoS) requirements, such as low latency, bounded jitter, and high throughput. An increasing number of DRE applications are developed using QoS-enabled middleware, such as Real-time CORBA and the Real-time Specification for Java (RTSJ), to ensure predictable end-to-end QoS. Real-time CORBA is an open middleware standard that allows DRE applications to allocate, schedule, and control the QoS of CPU, memory, and networking resources. The RTSJ provides extensions to Java that enable it to be used as the basis for Real-time CORBA middleware and applications.

This paper provides two contributions to the study of QoS-enabled middleware for DRE applications. We first outline key Real-time CORBA implementation challenges within the ORB Core and the Portable Object Adapter. We then describe how these challenges have been addressed in ZEN, which is an implementation of Real-time CORBA that runs atop RTSJ platforms. Our results show that the judicious application of optimization strategies can enable RTSJ-based Real-time CORBA ORBs to achieve effective QoS support for a range of DRE applications.
