关于数据访问编码参数的研究

On the Parameters of Codes for Data Access

Altan B. Kilic, Alberto Ravagnani, Emina Soljanin

AI总结:

本文研究编码分布式存储系统中服务速率区域包含指定点集时所需的最小服务器数与最小字母表大小,建立了严格上下界并给出基于编码理论、优化和射影几何的构造。

摘要:

本文研究编码分布式存储系统中与其性能直接相关的两个关键问题:1)在固定字母表大小的情况下,确定系统为使服务速率区域包含一组指定点而必须拥有的最小服务器数量;2)在给定服务器数量的情况下,确定系统服务速率区域包含一组指定点所需的最小字母表大小。本文建立了严格的上界和下界,并给出了基于编码理论、优化和射影几何技术的编码构造。

英文摘要:

This paper studies two crucial problems in the context of coded distributed storage systems directly related to their performance: 1) for a fixed alphabet size, determine the minimum number of servers the system must have for its service rate region to contain a prescribed set of points; 2) for a given number of servers, determine the minimum alphabet size for which the service rate region of the system contains a prescribed set of points. The paper establishes rigorous upper and lower bounds, as well as code constructions based on techniques from coding theory, optimization, and projective geometry.
