| Abstract: | The data volume and cost of information management and maintenance would sharply increased with the storage network scale enlarged, thus deteriorating the data service quality of networks for its extra management bur- den. In this paper, storage nodes were organized with semi-distributed topology method to optimize the network lay- out. The improved Chord protocol contributes to form autonomous region dynamically of large-scale discrete nodes and distribute hash table is good for efficient nodes inquiry and management. The management nodes were dynamically voted in autonomous region to keep highly stability of the self-organized system. Simulation results show that the average inquiry length would be decreased and the volatility lowered with the new method when network scale increased. |
