Configurable & Reconfigurable Group Services in a Component Based Middleware Environment

The past few years have seen a significant increase in the importance of group based distributed applications such as media dissemination, computer supported collaborative work or fault tolerance through replication. However, most distributed object based middleware platforms, which are increasingly being used as an implementation environment for such applications, fail to provide suitable support for group applications in their full generality. In this paper we describe a component based approach to the provision of group services in a middleware environment in which application tailored group services can be built by defining particular configurations of components or by incrementally modifying existing configurations. In addition, our approach uses reflective capabilities of the middleware platform to support the run-time reconfiguration of existing and running group applications.
