On demand logical resource replication scheme as a service

Abstract

Logical resource replication in cloud environment along with the issue of transparency and its impact on overall system performance has been rarely focused. This work proposes an On-demand Logical Resource Replication Scheme (OLRRS) for file replication. OLRRS approach provides migration, access and performance transparency to the system, thereby ensuring the migration decisions about the files. It is also responsible for replicating the file, from one peer server to the other peer server, when the total number of request, on a peer server, for transferring a file reaches the threshold value. The scheme is simulated on JAVA platform and tested on a private cloud. A comparative study of the pro- posed approach with the Request Reply Acknowledgement (RRA) and Request Reply (RR) protocol is presented, showing the significant reduction by 37.5% to 58%, in terms of total number of messages exchanged for replication. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
