Group model for decentralized federation of Object Creation service

Abstract

Distributed Object Technology is extending the traditional OO programming model into a distributed environment. It enables remote manipulation of distributed objects in a full lifecycle view. However, current technologies (CORBA or COM) either fail to address the object creation activity of the lifecycle in a balanced way, or are unable to give a proper model for implementing a federated Object Creation service network. In this paper we analyze and clarify some problems associated with object creation activity and service network organization, and propose a group model for implementing decentralized federation of the Object Creation service. After giving a thorough analysis and an implementation design for the model, we conclude that it is a clean-designed, very efficient, and extremely flexible model for our aim. Moreover this model not only ensures the location transparency and efficiency of Object Creation service for programmers, but also gives administrators a flexible, scalable method for managing the service network, which may dynamically restructure itself.
