Özet: Grid technology is a very promising solution for massive data applications. Data replication is one of the important techniques used in grid systems to increase the availability, scalability and fault tolerance. However, the update of a replica by grid users might bring a critical problem of maintaining data consistency among the distributed replicas. Thus, maintaining the consistency of the replicas is not trivial because of the instability of the grid resources. In addition, during Read/Write operation some nodes can be more loaded than the other and become a bottleneck. In this paper, we propose a model of consistency based on quorum protocol which is ameliorated by using a dynamic load balancing strategy.
