摘要
提出了一种基于Erasure code容错理论的分布式文件系统模型并对其关键技术进行了深入的研究和探讨。介绍了文件系统和分布式文件系统的概念,基于Erasure code理论提出了具有适度容错机制的分布式文件系统架构。详细讨论和分析了该系统实现中涉及的一系列关键技术,最后简短描述了本模型的实现,并给出了其性能评价。
This paper proposes a distributed file system model which is based on Erasure code theory, and discusses its key technologies and implementation. First it introduces some conceptions of file system as well as the distributed file system, then it brings forward a distributed file system model based on Erasure code. Afterward some solutions for the key technologies such as error correction, cache mechanism and garbage collection are given. Finally it comes with a brief implementation and evaluates the performance.
