Distributed　cache　technology　is　being　more　and　more　considered　to　apply　in　distributed　system　to　solve　the　system＇s　data　access　performance　bottleneck.　Because　there　are　some　defects　in　distributed　cache　system　such　as　the　data　backup　strategy,　we　designed　and　implemented　the　partition　replication-based　distributed　cache　system.　Partition　replication　method　reduced　the　network　data　transmission　load　during　replication　and　improved　overall　system　performance.　©　2010　IEEE.
