In recent years, several results have been introduced to enhance network performance. While much more efforts have focused on server load balancing. Load balancing (LB) of Grid systems have not been addressed so far. This paper, therefore, proposed dynamic load balancing for Grid systems in order to quickly render information to consumer requests. The proposed algorithm is based on migration the requests from Registry to failover registry if there are overloaded at Registry or Registry is failed. The new point in this algorithm is that the tasks will be ordered in ready queue of Registry or failover registry depending on the priority values (trust values of consumers). The proposed dynamic load balancing algorithm is evaluated by measuring response time, system utilization, and throughput. Finally, we compare all the types of LB algorithms with the proposed dynamic load balancing algorithm. It successes in reducing response time and increasing throughput.
