Abstract: We study the problem of centralized exact repair of multiple failures in distributed storage. We present constructions that achieve a new set of interior points under exact repair. The constructions build upon the layered code… read more here.

Abstract: For general exact repair regenerating codes, the optimal trade-offs between the storage size and repair bandwidth remain undetermined. Various outer bounds and partial results have been proposed. Using a simple chain rule argument, we identify… read more here.
