In this paper the authors study the QoS ensured optimal replica placement problem. Most of the studies on replica placement concerns only about minimizing the data access time, without considering the quality of service issue. In heterogeneous environments, the quality assurance is important. They propose an algorithm named Replica Placement in Graph Topology Grid (RPGTG), which optimally place the replicas and also ensures QoS. In this paper they study optimization problem, which addresses the issues, minimizing the data access time, load balancing among replica servers and avoiding unnecessary replications.
