DISQUEV: Looking for Distribution Quality Evolution as a New Metric for Evaluating Replication Strategies
Chamseddine Hamdeni, Tarek Hamrouni, Faouzi Ben Charrada · 2017
Replicating data through different storage elements in order to facilitate their access is a main feature in data grids. This helps reducing execution time and bandwidth consumption, ensuring load balancing, and increasing data availability and service quality. In this regard, several replication strategies have been proposed in the literature. In this work, a new evaluation metric called DISQUEV is proposed and experimentally evaluated. This metric will serve to tackle the evaluation of the impact of a replication strategy on the data distribution quality in the grid. The data distribution is indeed proven to have a close influence on the performances of the grid not only for its short term uses but also for the long term.
