Research Of Cloud Storage Model Based On P2P

Cloud storage had received extensive attention in the industry as its character of low cost, large capacity, flexible service etc. Cloud storage model mainly adoptsmaster/slave structure at present, all of the user’s request information centralizedprocessed by a central server, so it is easy to manage and the maintenance isconvenient, but the center server load is overweight, prone to problems of a singlepoint of failure and po or reliability. on the basis of the analysis of P2P network, thispaper proposes a model of cloud storage based on P2P.The cloud storage system is divided into multiple storage cluster, each storagecluster consists of a SuperNode of cluster head and multiple DataNode.all clusterheads make up a P2P network based on Kademlia protocol, the user’s request isdistributed to each SuperNode by Kademlia protocol, Kademlia protocol locatestorage cluster store information; Adopt traditional structure of cloud storage modelwithin storage cluster, cluster heads is located in the center server, it managementDataNode in the storage cluster to store data.The P2P network self-organized by cluster head, Kademlia protocol is adopted toimprove the routing in the P2P network, P2P network can solve the problem ofbottlenecks of master/slave structure network, makes the system has the advantages ofdecentralization, load balancing. Keep the master/slave structure within the storagecluster so that the cloud system will keep the convenience of data management andmaintenance. In order to improve reliability and availability of the system, this modelalso gave out copy redundancy strategy.The proposed method has simulation experiment and the result shows it iseffective and feasible.
