It has been almost a decade since the earliest reliable CORBA implementation and, despite
the adoption of the fault-tolerant CORBA (FT-CORBA) standard by the Object Management …

Distributed computing is one of the major trends in the computer industry. As systems
become more distributed, they also become more complex and have to deal with new kinds …

One way to implement a fault-tolerant service is by replicating it at sites that fail
independently. One of the replication techniques is active replication where each request is …

A three-tier application is organized as three layers: human users interact with front-end
clients (eg, browsers), middle-tier application servers (eg, Web servers) contain the business …

Software-based active replication is expensive in terms of performance overhead.
Multithreading can help improve performance; however, thread scheduling is a source of …

In CORBA-based applications that depend on object replication for fault tolerance,
inconsistencies in the states of the replicas of an object can arise when concurrent threads …

Data replication is playing an increasingly important role in the design of parallel information
systems. In particular, the widespread use of cluster architectures in high-performance …

The present invention relates to object serialization. More particularly, the present invention
relates to methods, sys tems, and computer program products for transforming objects of one …

We present a system architecture which facilitates enhanced availability of tightly coupled
distributed systems by temporarily relaxing constraint consistency. Three different types of …
