Erasure codes are being extensively deployed in distributed storage systems instead of
replication to achieve fault tolerance in a storage efficient manner. While traditional erasure …

We propose a generic transformation that can convert any nonbinary (n= k+ r, k) maximum
distance separable (MDS) code into another (n, k) MDS code over the same field such that …

We propose a generic transformation on maximum distance separable (MDS) codes, which
can convert any non-binary (k+ r, k) MDS code into another (k+ r, k) MDS code with the …

Minimum-Storage Regenerating (MSR) codes have emerged as a viable alternative to Reed-
Solomon (RS) codes as they minimize the repair bandwidth while they are still optimal in …

Piggybacking design has been applied extensively in distributed storage systems in recent
years, since it can reduce repair bandwidth significantly with small sub-packetization. In this …

Recently, some high-rate maximum distance separable (MDS) array codes were designed
to optimally repair a single failed node by connecting all the surviving nodes. However, in …

Piggybacking is a class of coding framework for MDS array codes that can achieve small
repair bandwidth with small sub-packetization. An (n,k,α) piggybacking code can be …

As a kind of erasure code, piggybacking has been applied in practice since it can
significantly reduce the repair bandwidth of distributed storage systems. Currently, several …

Most of the piggybacking designs can only effectively repair systematic nodes. In this letter,
we propose a new piggybacking method for repairing parity nodes based on the existing …

Piggybacking is an efficient framework to reduce the repair bandwidth of distributed storage
systems, especially, when the systems meet the settings-maximum distance separable …
