一类精确修复多个错误的Suh-Ramchandran码
Class of Suh-Ramchandran codes with exact multi-failure repair
摘要
Abstract
Regenerating codes are more suitable for distributed storage system since it can effectively reduce the repair bandwidth.By using the interference alignment technique,Suh-Ramchandran constructed a class of minimum storage regene-rating codes,which could repair a single failure node with optimal repair bandwidth for any parameters (n,k,d)such that n ≥ 2k and d≥2k-1.This paper redescribed a class of codes with parameters (n =2k + 1;k) based on Suh-Ramchandran regenerating codes,and shows that the constructed minimum storage regenerating codes could achieve optimal repair bandwidth for either single or multiple nodes failure repair.关键词
