An access-tendency based dynamic replica creation strategy for data grid
摘要
Abstract
Current hot data select in replica creation strategies didn’t react to data mutation and resulting in replicas create and delete frequently and then caused grid thrashing .According to this ,an access-tendency based dynamic replica creation strategy (ADRS) is proposed .ADRS calculate file’s access-tendency based on historical data access ,and then according to file’ s access-tendency create or delete replica .T he simulation results show that ADRS can reduce the replica create times and increase replica usage rate for random access pattern compared to Latest-access-largest-weight algorithm (LALW) and didn’t affect the efficiency w hen node’s space is limited .关键词
