Using Real-Time Java in Distributed Systems: Problems and Solutions

Many real-time systems are distributed, i.e. they use a network to interconnect different nodes. The current RTSJ (Real-time Specification for Java) specification is insufficient to address this challenge; it requires distributed facilities to control the network and maintain end-to-end real-time performance. To date, the real-time Java community has produced the DRTSJ (The Distributed Real-Time Specification for Java), though a wide variety of other distributed real-time Java efforts exist. The goal of this chapter is to analyze these efforts, looking for the problems they addressed and their solutions, and defining (when possible) their mutual relationships.
