Study on Redundant Strategies in Peer to Peer Cloud Storage Systems

Abstract

Relative to the current Master/Slave computing model cloud storage file systems, including GFS, HDFS, Sector, we proposed a general model of Peer-to-Peer based Cloud Storage file system, and constructed a prototype system named MingCloud based on Kademlia algorithm. Focused on redundant strategy selection and design of the storage system, our experiment used the Cauchy Codes as coding algorithm to assess the system from many aspects. Compared with the redundant mode of complete copy, Erasure Code model provided more satisfactory system availability, and more suitable to apply to our P2P Cloud Storage System.
