Java based replicated server objects and their remote method invocations in a distributed environment

摘要

A distributed system is said to be fault-tolerant if it is able to provide important services despite partial failures of the computers or software objects in the system. These systems are needed to support applications such as remote access and control, virtual mobile offices and wide area collaborative systems where there are chances of failures in the network and software objects. Fault-tolerance is usually achieved by replication the objects in the system. Traditional distributed applications constructed using Java RMI (remote method invocation) are not fault-tolerant because of the lack of support of object replication.
