Title:A Hybrid Approach for Replica Placement-Replacement (Harp-R Algo) Algorithm In Data-Grid
Author Name:Ashish Kumar Singh and Udai Shanker
Synopsis:
Distributed database system is a network in which multiple clients are connected logically, but physically they are distributed and each client has their own database. Replication process in such a environment plays a vital role for reducing response time. The process of creating exact copy of file is known as replication. Replication process can be executed in two ways, one is static replication and another is dynamic replication. In a static replication, created replica exist in the system till user deletes it manually or it’s time expired. In dynamic replication, it will behave with change in user behavior and it will automatically create new replicas or delete replicas to improve performance. Data replication, as one of the popular services in a distributed database system, is used to increase the data availability and scalability. In this paper, the authors have proposed a data replication protocol in which they replicate those file which are popular in all, and replication process for those file whose success rate is high. In this paper proposed system uses the advantages of both static and dynamic replication.
