一种基于P2P的云存储模型研究

A Cloud Storage Model Based on P2P

在分析当前云存储系统所面临的问题的基础上,提出一种基于P2P技术的云存储模型。此模型应用Chord算法来组织节点并分发用户的请求,解决集中式云存储系统的中心节点瓶颈问题,实现系统的负载均衡;使用存储簇来完成数据的存储和管理,简化系统管理的难度;并提出模型的副本管理策略,使云存储系统具有良好的可扩展性、容错性和高性能。

After analyzing the problems of current cloud storage, this paper presents a new cloud storage model based on P2P. This model applies Chord arithmetic in managing nodes and handing out clients＇ requests, which solves the prob- lems from the centralized structured architecture such as SPOF, performance bottleneck and so on, and realizes load bal- ancing. The model takes advantage of storage clusters to manage users＇ data, which simplifies the difficulty of system management. Also a replica management strategy is applied in this model, which achieves better scalability, fault tolerance and enhanced performance.
