Dynamic replication is a technique that can be used by clustered multimedia servers to evaluate the demand for individual streams and selectively replicate or move content to facilitate load balancing. In this paper we explain the motivation for using dynamic replication and provide a brief description of some existing dynamic replication policies. We present a new policy called Dynamic RePacki...

Data replication is a common method used to improve the performance of data access in distributed systems. In this paper, two dynamic replication algorithms, Simple Bottom-Up (SBU) and Aggregate Bottom-Up (ABU), are proposed for the multitier Data Grid. A multi-tier Data Grid simulator called DRepSim is developed for studying the performances of the dynamic replication algorithms. The simulatio...

Failures are usual rather exceptional in cloud computing environment. To access from the nearby site, the often used data should get replicated to multiple locations to compose the users to advance the system accessibility. A challenging task in cloud computing is to decide a sensible number and right location of replicas. At this point, we propose an adapted dynamic data replication approach t...

This paper proposes a protocol suite for dynamic replication and migration of Internet objects. It consists of an algorithm for deciding on the number and location of object replicas and an algorithm for distributing requests among currently available object replicas. Our approach attempts to place replicas in the vicinity of a majority of requests while ensuring at the same time that no server...
