This paper describes the research into the design of a configurable and reconfigurable group service for middleware. The main objective is to allow components of a group service to be changed at run time using reflection and component architecture technology. 1 Introduction Distributed applications such as video-conferencing, video-on-demand, CSCW, web casting, and distributed simulation are demanding new features from the underlying platforms. One example is the support for groups of users where multiple senders and receivers disseminate or share the same data. Improvements in communication technology have brought an efficient solution for dealing with a set of users as a single entity and using multipoint communication (multicast) to send the same data to each member of the group. Our concern in this paper is related to the complexity involved in the development of group applications. Although a simple multicast facility can be suitable for some cases, more complex requirements can ...
