Three-tier replication for FT-CORBA infrastructures

Roberto Baldoni, Carlo Marchetti
2003 Software, Practice & Experience  
Then we present the interoperable replication logic (IRL) architecture, a fault-tolerant CORBA compliant infrastructure.  ...  IRL exploits a three-tier approach to replicate stateful deterministic CORBA objects and allows object replicas to run on object request brokers from different vendors.  ...  Finally, the authors thank Paolo Papa, Alessandro Termini and Luigi Verde for their contributions to the IRL prototype and Stephen Kimani for his kind and valuable help.  ...

Gateways for Accessing Fault Tolerance Domains [chapter]

P. Narasimhan, L. E. Moser, P. M. Melliar-Smith
2000 Lecture Notes in Computer Science  
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  ...  Gateways can allow unreplicated clients to benefit from the fault tolerance services of the replicated servers, without compromising replica consistency within the fault tolerance domain.  ...  A key issue in fault tolerance for CORBA will be the mechanisms to support interaction of non-fault-tolerant CORBA systems with fault-tolerant CORBA systems.  ...
