摘要

我们提出了一种存储优化和计算效率高的原语,将信息从单个数据源传播到一组存储节点,以允许从崩溃停止和拜占庭故障中恢复。采用渐进式数据检索方案,从活动存储节点中检索最少量的数据。该方案将成功检索数据的代价与系统中的错误程度相适应。实施和评估研究表明,性能相当的一个基因辅助解码过程。

Survivable Distributed Storage with Progressive Decoding
We propose a storage-optimal and computation efficient primitive to spread information from a single data source to a set of storage nodes, to allow recovery from both crash-stop and Byzantine failures. A progressive data retrieval scheme is employed, which retrieves minimal amount of data from live storage nodes. The scheme adapts the cost of successful data retrieval to the degree of errors in the system. Implementation and evaluation studies demonstrate comparable performance to that of a genie-aid decoding process.
