Alireza Souri, Amir Masoud Rahmani · International Journal of Modern Education and Computer Science · 2014
In data grids, data replication on variant nodes can change some problems such as response time and availability.Also, in data replication, there are some challenges to finding the best replica efficiently in relation to performance and location of physical storage systems.In this paper, various replica placement strategies are discussed.These replica placement strategies are available in the works.Replica placement contains recognizing the best possible node to duplicate data based on network latency and user request.These strategies measure and analyze different parameters such as access cost, bandwidth consumption, scalability, execution time and storage consumption.This paper also analyses the performance of various strategies with respect to the parameters mentioned above in data grid.
