摘要

本文描述了基于分布式实时对象(DRO)模型的c++扩展的分布式实时编程语言DROL支持的对象间通信协议的语义。这些协议的一个共同特点是引入了一个新概念:最少的痛苦。最小的损失确保用户在所需的时间限制内收到网络故障通知，并从中快速恢复。因此，这个概念允许用户在广泛分布的环境中构建实时应用程序。以前提出的实时编程语言不可能做到这一点。通过对应用程序的描述和对其行为的讨论，我们证明了最小痛苦的有效性。

Constructing distributed real-time systems with DROL real-time objects

In this paper, the semantics of inter-object communication protocols supported by the distributed real-time programming language DROL that is an extension of C++ based on the Distributed Real-time Object (DRO) model is described. A characteristic common to these protocols is the introduction of a new notion, least suffering. The least suffering assures users of notification of network faults within a required timing constraint and rapid recovery from them. Thus, this notion allows users to construct real-time applications on widely distributed environments. It is impossible for previously proposed real-time programming languages to do it. Through the description of application programs and the discussion of their behavior, we show the effectiveness of the least suffering.
