摘要: Groupware and fault-tolerant distributed systems stimulate the need for structuring activities around object-groups reliable multicast communication. The object-group abstraction permits to treat a collection of network-objects as if they were single object; clients can invoke operations on without needing know exact membership group. Object-groups mainly serve increase reliability through replication, performance parallelism, or distribute data from one sender large number receivers efficiently. This paper describes how communication be added CORBA compliant Object Request Broker. It also presents ELECTRA -- Broker whose architecture is pervaded by group concept.
