一类精确修复多个节点的简单再生码
A CLASS OF SIMPLE REGENERATING CODES CAPABLE OF EXACT MULTI-NODE REPAIR
摘要
Abstract
Massive data environment requires the storage system with the characteristics such as high scalability,high reliability and low price,etc.However,the nodes in large-scale storage system will frequently failure due to too huge in number.In order to ensure the usability of nodes,the system will use redundancy data to repair the failure nodes.As a new fault-tolerant technology,regenerating code can effectively reduce the amount of the download data required when repairing the failure nodes in distributed storage system.In this paper,we design a new encoding mode for distributed storage system based on simple regenerating codes.This mode can not only tolerates the simultaneous errors of multiple nodes and repairs them,but also has simple encoding form and achieves higher code rate.关键词
