在本文中，我们介绍了一个模型的单故障本地可恢复的分布式存储系统。这个模型似乎引起了一个问题，近似对偶的研究良好的索引编码问题。本文建立了模型的最优索引码和最优分布存储码的维数之间的关系。我们还展示了向量码的一些扩展。
In this paper, we introduce a model of a single-failure locally recoverable distributed storage system. This model appears to give rise to a problem approximately dual of the well-studied index coding problem. The relation between the dimensions of an optimal index code and optimal distributed storage code of our model has been established in this paper. We also show some extensions to vector codes.
