A Fast Group Communication Mechanism for Large Scale Distributed Objects

Group communication undoubtedly is a useful paradigm for many distributed object systems. Provision of a fast and scalable group communication mechanism can considerably improve the efficiency of these systems. In this paper, we propose a new group communication mechanism for large scale distributed objects over a huge heterogeneous inter-network. The proposed mechanism uses Message Dispatcher Objects, objects co-located with each group member to distribute and parallelize the group communication load among all group members. Our proposed mechanism also recovers from the host failure in the system. Experimental results show that our scheme scales well in a large number of group members.
