  Replication is a well known technique to improve reliability and performance for a Data Grid. Keeping consistent content at all distributed replica is an important subject in Data Grid. Replica consistency protocol using classical propagation method called the radial method suffers from high overhead at the master replica site, while line method suffers from high delay time. In Data Grid not all replicas can be dealt with in the same way, since some will be in greater demand than others. Updating first replica having most demand, a greater number of clients would access the updated content in a shorter period of time. In this study, based on asynchronous aggressive update propagation technique, a scalable replica consistency protocol is developed to maintain replica consistency in data grid which aimed to reaching delay reduction and load balancing, such that the high access weight replicas updated faster than the others. The simulation results shows that the proposed protocol is capable of sending the updates to high access replicas in a short period while reducing the total update propagation repose time and reached load balancing.
