摘要:Optimal node repair in coding for distributed storage systems is a central topic. However, existing high-rate maximum distance separable (MDS) codes with the optimal repair bandwidth require a significantly large sub-packetization level, which may prevent the codes to be implemented in practical systems. In this talk, we first introduce a generic transformation that can convert any nonbinary MDS code into another one such that some target nodes can be optimally repaired, and then present another transformation that can greatly reduce the sub-packetization level of high-rate MDS codes with the optimal repair bandwidth.
