Abstract

In this paper, we propose a novel cooperative repair scheme for Zigzag MSR codes with optimal repair bandwidth, enabling the repair of any h failed nodes. To the best of our knowledge, this is the first optimal cooperative repair scheme for Zigzag MSR codes. Compared to previous cooperative repair schemes for MSR codes, our scheme significantly reduces the size of the finite field to Fq,q>=n+1.
