An architecture for distributed real-time Java based on RMI and RTSJ

Abstract

Today's trend in real-time systems reveals the necessity of new technologies to easy their development and maintenance. Among others, some interesting alternatives are found in high-level real-time programming languages, better development models, or simple architectures and models. From the perspective of real-time Java, a recent real-time programming language, this paper offers an architecture (and its corresponding Java interfaces) to help the development of an upcoming distributed real-time technology for Java (named DRTSJ). To that end it describes a neutral architecture based on Java's Remote Method Invocation (RMI) and The Real-time Specification for Java (RTSJ). The empirical evidences included in the paper offer also interesting clues on the performance this technology may deliver.
