Outer bounds on the storage-repair bandwidth trade-off of exact-repair regenerating codes
Outer bounds on the storage-repair bandwidth trade-off of exact-repair regenerating codes
In this paper, three outer bounds on the normalised storage-repair bandwidth trade-off of regenerating codes having parameter set {(n, k, d), (α, β)} under the exact-repair (ER) setting are presented. The first outer bound, termed as the repair-matrix bound, is applicable for every parameter set (n, k, d), and in …
