码的服务率问题的几何观点及其在一阶Reed-Muller码服务率中的应用

A Geometric View of the Service Rates of Codes Problem and its Application to the Service Rate of the First Order Reed-Muller Codes

Fatemeh Kazemi, Sascha Kurz, Emina Soljanin

摘要:

服务率是一个重要的,最近推出的,与分布式编码存储系统的性能指标。在其他解释中,它测量存储系统可以同时服务的用户数量。我们引入几何方法来解决这个问题。与现有方法相比,这种方法最显著的优点之一是,它允许人们在不明确知道所有可能的恢复集的列表的情况下导出代码的服务速率的界限。为了说明我们的几何方法的力量,我们推导出一阶Reed-Muller码和单纯形码的服务率的上界。然后,我们将展示如何实现这些上界。此外,利用所提出的几何技术,我们表明,给定的服务率区域的代码,代码的最小距离的下限可以得到。

英文摘要:

Service rate is an important, recently introduced, performance metric associated with distributed coded storage systems. Among other interpretations, it measures the number of users that can be simultaneously served by the storage system. We introduce a geometric approach to address this problem. One of the most significant advantages of this approach over the existing approaches is that it allows one to derive bounds on the service rate of a code without explicitly knowing the list of all possible recovery sets. To illustrate the power of our geometric approach, we derive upper bounds on the service rates of the first order Reed-Muller codes and simplex codes. Then, we show how these upper bounds can be achieved. Furthermore, utilizing the proposed geometric technique, we show that given the service rate region of a code, a lower bound on the minimum distance of the code can be obtained.
