Gateways for Accessing Fault Tolerance Domains

Enterprise applications can be structured as domains, where each domain contains objects that are replicated for fault tolerance, with the replication being managed by a fault tolerance infrastructure local to the domain. Gateways can allow unreplicated clients to bene t from the fault tolerance services of the replicated servers, without compromising replica consistency within the fault tolerance domain. For CORBA-based enterprise applications, the gateway mechanisms can be implemented transparently to the ORB and to the application using interception speci c enhancements to existing ORBs make it possible for unreplicated clients to enjoy a higher degree of reliability.
