Distributed object applications can be made fault tolerant by replicating their constituent objects, and by distributing these replicas across the different computers in the network. The idea behind object replication is that the failure of one replica of an object can be masked from a client of the object because the other replicas can continue to perform any operation that the client requires. We propose IFTS (Intelligent Fault Tolerant CORBA Service) for handling faults of server object replica using a replication concept to support fault tolerance. It can choose the fastest primary replica using the multicast mechanism. It also introduces passive replication for secure fault tolerance. Furthermore, we propose the design and implementation of IFTS service to provide reliability and faster service using multicast technology by extending existing CORBA ORB.
