Implementation of a transparent RPC for distributed object-oriented systems

In this paper we describe a remote procedure call (RPC) mechanism that is used to implement the object oriented programming language Deal. Deal (Dedos Application Language) is a C++-based language that supports real-time and concurrency and is developed in the context of the Dependable Distributed Operating System (Dedos) project at Eindhoven University of Technology. An essential aspect of the presented RPC mechanism is that it helps to hide distribution from the programmer during program construction and provides the Deal programmer with the abstraction of a single object space. The design of the (C++) classes that implement the RPC mechanism is described in detail.
