%0 Journal Article %T On P2P and Hybrid Approaches for Replica Placement in Grid Environment %A Qaisar Rasool %A Jianzhong Li %A Shuo Zhang %A Ehsan Ullah Munir %J Information Technology Journal %D 2008 %I Asian Network for Scientific Information %X In this study, we present a review of replication techniques that work under peer-to-peer, hybrid and domain-based approaches for Grid environment, with specific emphasis on replica placement. We identify that peer-to-peer technology is contributing a high proportion in Grid data management and replication. A representative set of replica placement schemes were simulated and compared to show their effectiveness. %K peer-to-peer %K Data Grid %K data replication %K replica placement %U http://docsdrive.com/pdfs/ansinet/itj/2008/590-598.pdf
