Abstract :
LandHouse is a distributed storage system that is made up of some regular graphs and is organized by distributed hash table. However, the master server is the performance bottleneck of LandHouse. Moreover, when using traditional data block strategy, the regular graph Petersen can´t work to its best extent. Therefore, a new architecture with modified node deployment is designed to optimize the original system. Besides, a novel data block strategy named FTF using erasure code technology and an improved dynamic load balancing algorithm on Petersen Ring are proposed. Simulation results show that these modifications can improve robustness and performance of the system effectively.
