| 摘 要： | 随着P2P应用的发展，由以往共享只读文件逐渐改变为共享可读写的文件，文件的频繁更新导致了数据副本之间的不一致性，因此确保其副本一致性是保证正确运行的关键。通过文献调研，对目前国内外研究的副本一致性算法进行了详细的介绍，分析了各种算法的优缺点，并在现有算法的基础上进行了展望，提出下一步研究的方向和重点。

| Abstract: | With the increasing P2P application, read-write files are shared in the P2P networks instead of read-only files. The replicas are not consistent consistency is the key to ensure it running correctly. This paper introduced several replica consistency algorithms in detail and analyzed their strength and weakness. Based on these algorithms, this paper outlined the future directions and key points. |
