Group Communication Support for Dependable Multi-User Object Oriented Environments
Hugo Miranda, Miguel Antunes, Luı́s Rodrigues, António Rito Silva · 2000
Distributed multi-user interactive systems have a rich and complex set of requirements including the need for dependable operation. A promising approach to tackle the complexity of these systems is to rely on configurable architectures that are able to support component re-utilization and composition. The MOOSCo project, Multi-user Object-Oriented environments with Separation of Concerns, addresses the difficulties in applying a component-based approach in a vertical and integrated manner, from analysis to implementation, to the design of this class of systems. To support communication among distributed entities, the project will use a configurable group communication system called Appia. The paper discusses the role of Appia in the MOOSCo architecture. 1. Introduction Distributed multi-user interactive systems are an extremely relevant application area. Applications such as virtual environments, distributed simulation, computer supported collaborative work (CSCW), multi-user games o...
