Design of Dynamic Replication Strategies for a Grid Computing

Grid computing is growing more successful in distributed computing. It is a important method to solve complex application. This paper outlines the definition of grid computing, its specialty and fundamental structure, it specially debates large amounts of data to be able to share and distributed. The paper introduces dynamic replication in a grid scenario, which can be used as a technique to reduce bandwidth consumption and enhance access latency. The performance of six different replication strategies for three different kinds of access patterns is evaluated.
