  • Current trends in real-time systems identify Java as a new alternative to develop both centralized and distributed real-time systems. Many efforts have been devoted to develop the Real-Time Specification for
    Java (RTSJ), and there is substantial ongoing activity to produce a
    straightforward and valuable Distributed Real-Time Specification for
    Java (DRTSJ). The current paper provides a contribution to this latter
    activity defining, from different angles, a synchronous scheduling
    service aligned with principles of some popular real-time architectures.
    This service orchestrates the system in such a way that it provides
    end-to-end guarantees in the distributed transactions, guaranteeing
    their timely execution across the network and nodes. The service is
    described from two points of view: the system one, characterizing a
    portable model; and the programmer one, defining a distributed
    object-oriented implementation of a model based on Real-Time Remote
    Method Invocation (RTRMI). Finally, it also presents results of an
    implementation carried out to judge the efficiency of the service,
    offering a preliminary predictability and performance assessment of a
    distributed real-time Java technology.
