Distributed object applications can be made faulttolerance by replicating their constituent object, and by distributing these replicas across the differentcomputers in the network.The idea behind objectreplication is that the failure of one replica of an objectcan be masked from a client of the object because theother replicas can continue to perform any operationthat the client requires.In this paper, we propose IFTS (Intelligent Fault-TolerantCORBA Service) in handling faults of server object replicausing replication concept to support fault tolerance.And it can choose the fastest primary replica using multicast mechanism.And it also introduces passive replication for secure fault tolerance.Furthermore, we propose the designand implementation of IFTS service to provide reliability and faster service using multicast technology by extendingexisting CORBA ORB.
