2104.01652 Nonlinear Repair Schemes of Reed-Solomon
· Abstract The problem of repairing linear codes and in particular Reed Solomon (RS) codes has attracted a lot of attention in recent years due to their extreme importance to distributed storage systems. In this problem a failed code symbol (node) needs to be repaired by downloading as little information as possible from a subset of the remaining nodes.

· is shown that when repairing a single failed storage node regenerating codes use less repair bandwidth than conventional Reed-Solomon codes 18 by transmitting encoded data from the surviving nodes to a new node. Also 7 gives an optimal tradeoff spectrum between storage cost and repair bandwidth and identifies two extreme points.
