Improving the Efficiency of Replication for Highly Reliable Systems

چکیده
Fault Tolerance must be provided to increase system reliability. Combining efficiency with fault tolerance is a difficult task. Fault Tolerance requires the use of redundancy while efficiency requires the elimination of redundancy. Several fault tolerance techniques have been proposed in the literature to manage the redundancy existing in the system in order to provide fault tolerance. These techniques focus mainly on providing fault tolerance. We propose a technique named Active Parallel Replication (APR) for managing the redundancy existing in the system. The APR technique provides the means to achieve fault tolerance and efficiency.
