Abstract

As ISDNs develop, distributed applications on these networks will increase in number, scope and complexity. The distributed application environment will become more and more complicated. Distributed applications are as varied as application environments, requiring cooperations between them in different ways and to different extents. We describe here a new model that is designed to support distributed applications, called the Associated Object Model. In this model, multi-objects can communicate with each other through an abstract association, making it possible for application objects to cooperate in wider degree than was possible before. A mechanism supporting associations, broker, is introduced in this paper. By the mechanism, many associations between cooperating application objects can be established and maintained. The paper also includes some discussions about the description and implementation of the model and the mechanism.
