Abstract

High availability is important for large scale distributed systems. Replication provides effective ways to enhance performance, high availability and fault tolerance in distributed systems. An efficient and effective replication technique is the key to improve the availability performance. Data and processes can be replicated for failures recovery. There are currently projects successfully implemented in two-replica distribution technique (TRDT) or primary–backup technique. However, these projects have their weaknesses of increasing cost overhead and inherit irrecoverable scenarios from TRDT such as double faults when both copies of replicated components are damaged. The authors propose the Neighbor Replica Distributed Technique (NRDT) availability prediction model. Focusing on improving high availability in which it predicts future expectation of interdependent server’s availability in a distributed online system over an extended period of time. The results and discussion are explored further in the article.
