P2P存储环境下的稳固冗余存储方案设计

Design of the persistent redundancy storage scheme in P2P environment

大规模P2P稳固冗余存储方案是当前存储研究领域的研究热点。从存储组织结构和数据维护机制两个方面出发,重点比较了完整模式、编码模式和混合模式的数据存储特点;并在分析不同数据维护机制的基础上,提出一种具有失效置信度的数据延时维护策略。通过仿真实验验证了不同存储模式下的维护机制有效性和相关指标。

The scheme of the P2P persistent redundancy storage is an important issue in current research areas. The paper focused on two main points： the storage organizational structure and data maintenance mechanism. First the paper deeply compared the characteristics of the complete, coded and hybrid data storage modes. Second based on the analysis of the data maintenance mechanism, the paper proposed one kind of data time-delay maintenance strategy with failure confidence. At last the paper discussed the validity and related indicators of the maintenance mechanism in different storage modes through simulation.
