| 摘要: |
| 在充分考虑P2P存储特点的前提下，设计了一种新颖的基于Erasure Code的分割文件P2P存储方案，构建Chord协议上的P2P文件存储结构。通过设计有效的文件存储、访问和更新功能，克服传统Erasure Code冗余文件存储方案的不足，使存储文件具有一定的数据修改能力和结构伸缩能力。理论分析和实验仿真验证了设计方案在P2P存储系统中的可行性和有效性。 |

| Abstract: |
| In view of the characteristics of P2P storage, a novel Erasure Code based segmented file P2P storage strategy is designed, and the Chord protocol based P2P storage structure is constructed. The effective file storage, access and update function of the novel strategy overcome the deficiencies of the traditional Erasure Code P2P storage strategy, enabling the stored file to have a certain data revision capability and structure expansion-contraction capability. Theoretical analysis and experimental simulation verify that the novel strategy has reasonable feasibility and effectiveness. |
