Data Replication in large scale distributed systems was introduced for enhancing data availability, reducing network flow and access latency. Efficient selecting the best replica to minimize access latency remains a fundamental challenge. Existing algorithms mostly use the previous history of replica transfers stored locally to estimate the replica access time for selection replica. It will not always give the best result especially stale access replica log. In this research, we propose a… CONTINUE READING
