Group communication models

This paper presents an abstract model of an ODP-based group communication platform. The focus of this paper is on the computational and engineering models of a group communication environment. The group interaction requirements of advanced cooperative applications structured as an object-group are identified, and the distributed object models for group support are presented. The paper develops the notion of a policy-driven group support machine which can be used as a prototype model for integration in object-based platforms such as CORBA, DCE and TINA-DPE.
