针对云存储中现有多节点失效修复模型的不足,给出了一种可以对多个系统节点或冗余节点同时修复的多节点协作的精确修复码,证明了其存在性,并且将此修复码与具有健康节点协作的MDS双码架构模型相结合,以达到对多节点修复的同时,降低修复带宽、修复链路数和单个中间节点需要处理的数据量。通过数值仿真结果表明,本模型与修复方案在以上3个方面具有较大改进,尤其削弱了修复时中间节点的负荷,且随着云存储中节点数量的增多,本方案的优势更加明显。
A multi-node exact repair code scheme
which can repair multiple system nodes or redundant nodes simultaneously
was shown and proved to against the disadvantages of the existing multi-node repair model in cloud storage.The multi-node exact repair code was combined with a twin-MDS codes framework with health cooperative nodes.In this way
repair bandwidth
the number of repair links and the amount of data to be treated in an intermediate node were reduced
while multi-node were repaired.Finally
numerical simulation results show that this scheme has greater improvements.In particular
it reduces the load in an intermediate node.And the advantages was more obvious with the more storage nodes in cloud storage.
