FT_HORB : A Fault-Tolerant Distributed Programming Environment Based on RMI

In distributed systems, the provision for failurerecovery is always a hot design issue, whereas no fault-tolerant feature has been extensively considered in the current RMI, CORBA and other OODP environments. As a result, application developers have to implement their own fault tolerant mechanisms. In this paper, we propose a fault-tolerant development environment based on one kind of RMI, called FT_HORB, as a Java extension for the reliable distributed computing with checkpoints and rollback-recovery mechanism. The FT_HORB is inplemented on the Sun Ultra10 workstations connected through a 100 Mbps network. We observe that experimental applications on the FT_HORB can continue their operations in spite of hardware and software failures. Three benchmark models such as the nqueens problem, the traveling salesman problem and the gaussian elimination problem are experimented with the FT_HORB to evaluate its performance. The results show the performance of FT_HORB is acceptable. In addition, experiments demonstrate its possibility of extension to fully support our optimal design goal.
