Data partitioning is the basis of massive data distributed storage management and consistent hashing algorithm is one of the most popular data partitioning methods. We analyzes consistent hashing algorithm and find it can not guarantee the dynamic load balancing of the nodes in the system during the running time. To solve this problem, we propose a consistent hashing based data redistribution algorithm (CHRA). And the comparison of our simulation experiments verifies that the CHRA can balance the load of nodes in the system.
