Abstract

We present an architecture that addresses the heterogeneity of distributed environments by enabling Java distributed real-time processing. Our framework can be used to build real-time Java virtual manufacturing devices that operate over ATM networks. The Java virtual machine is hosted by a custom version of the Chorus distributed real-time operating system. Provided extensions include earliest deadline first scheduling and real-time IPC service over ATM. This paper summarizes the problems raised by Java in a real-time context and introduces our architecture. Then, we detail the improvements made to the JVM and the way it uses our real-time services. Transfer rates up to 97 Mbps are substained between distributed Java objects within our testbed cluster
