Replica Placement Strategy Research in Education Resource Grid
Replication mechanism is the efficient method of improving grid performances and reducing client delay. Replica placement strategy is the key problem of replication mechanism. This paper introduces the architecture of education resource grid. According to the architecture, it presents three dynamic replica placement strategies. These strategies can optimize the system performance from different aspects and reduce client delay on the premise of keeping the storage space of replica. These strategies are proved to be effective by analyzing experiment data.
