A Model of Replication Creation in Distributed Networks

Abstract:

Data Grid provides geographically distributed data resources. However, ensuring efficient and fast access to such huge and widely distributed resources is hindered by the high latencies of the Internet. Replication is adopted to address these problems. Aimed to replica creation, a model to decide replica creation opportune moment is introduced, which is based on queuing theory. Through statistical record of the arrival rate of uses, service period, and replicas already created, calculating length of queue, waiting duration time, busy period, service strength and so on, a reasonable creation opportune moment of replica can be obtained.
