Systems with cash memory (or more generally, with distributed memory) are very widely used in information technologies. Such are content delivery networks (CDN) of various types, which deliver digital movies, books, and similar content; peer-to-peer (P2P) networks, where millions of members exchange various information; and many other systems and devices of this kind. We introduce the notions of capacity and entropy efficiency for distributed memory systems, propose methods for estimating these quantities, and give an example of their application.

信息理论方法估计分布式存储系统的容量

具有现金存储（或更普遍地说，具有分布式存储）的系统在信息技术中得到了广泛的应用。各种类型的内容交付网络（CDN）可以交付数字电影，书籍和类似内容；点对点（P2P）网络，数百万成员在其中交换各种信息；以及许多其他此类系统和设备。我们介绍了分布式存储系统的容量和熵效率的概念，提出了估计这些数量的方法，并给出了其应用示例。
