Distributed object oriented architectures

Más información sobre el libro

This document offers a detailed discussion of selected distributed object-oriented architectures at a conceptual level. It begins with an overview of the Socket architecture in Java 2 and Berkeley UNIX, alongside the distributed object models of Java Remote Method Invocation (RMI) and the Common Object Request Broker Architecture (CORBA). The discussion concludes with a comparative study of features, focusing on CORBA and Java RMI. Key topics include: - **TCP/IP Protocol Suite**: An introduction to the TCP/IP architecture, covering its layers and protocols, based on processes, layers, and protocols. - **Sockets in Berkeley Unix**: An exploration of the Berkeley UNIX socket architecture in the context of Internet communication, highlighting connection-oriented and connectionless communication models. - **Sockets in Java 2**: A description of Java 2's socket architecture, selected socket operations, related packages and classes, and a framework for both connection-oriented and connectionless communication. - **Remote Method Invocation in Java 2**: An overview of the distributed object model in Java RMI, including related interfaces, classes, packages, and security considerations, culminating in a framework for a distributed object application. - **Common Object Request Broker Architecture**: An introduction to CORBA's distributed object model, design concepts like the Interface Definition Language and the Interoperable Naming
