S.O.V.O.R.A.: A Distributed Wireless Operating System

Distributed Application Operating System Operating System Api

Middleware is a class of software technologies designed to help manage the complexity and heterogeneity inherent in distributed systems. It is defined as a layer of software above the operating system but below the application program that provides a common programming abstraction across a distributed system, as shown in Figure 1. In doing so, it provides a higher-level building block for progr...

Helios - A Distributed Operating System

CHORUS Distributed Operating System

The Cnonus technology has been designed for building o'new generations" of open, distributed, scalable Operating Systems. CHoRus has the following main characteristics: ¡ Ír comÍ[tnication-based technology, relying on a minimal Nucleus integrating distributed processing and communication at the lowest level, and providing generic services used by a set of subsystem servers to provide extended s...

PM: A Distributed Object-Oriented Operating System

The PM project is introduced. Its goal is the design of a distributed object-oriented operating system. One of the research activities is the design of an object model for distributed object-oriented programming. This position papers presents the PM Object Model approach to distribution, concurrency control and object interaction. The system consists of an application system, a distribution sys...

The Evolution of a Distributed Operating System

AMOEBA is a research project to build a true distributed operating system using the object model. Under the COST11-ter MANDIS project this work was extended to cover wide-area networks. Besides describing the system, this paper discusses the successive versions in the implementation of its model, and why the changes were made. Its purpose is to prevent ourselves and others from making the same ...
