Bounds and Constructions for Linear Locally Repairable Codes over Binary Fields
Anyu Wang, Zhifang Zhang, Dongdai Lin
For binary linear locally repairable codes (LRCs), two new upper bounds on are derived. The first one applies to LRCs with disjoint local repair groups, for general v…
Achieving Arbitrary Locality and Availability in Binary Codes
Anyu Wang, Zhifang Zhang
The th coordinate of an code is said to have locality and availability if there exist disjoint groups, each containing at most other coordinates that can…
An Integer Programming Based Bound for Locally Repairable Codes
Anyu Wang, Zhifang Zhang
The locally repairable code (LRC) studied in this paper is an linear code of which the value at each coordinate can be recovered by a linear combination of at most othe…
Repair Locality From a Combinatorial Perspective
Anyu Wang, Zhifang Zhang
Repair locality is a desirable property for erasure codes in distributed storage systems. Recently, different structures of local repair groups have been proposed in the definition…
Repair Locality with Multiple Erasure Tolerance
Anyu Wang, Zhifang Zhang
In distributed storage systems, erasure codes with locality is preferred because a coordinate can be recovered by accessing at most other coordinates which in turn greatly…
Exact Cooperative Regenerating Codes with Minimum-Repair-Bandwidth for Distributed Storage
Anyu Wang, Zhifang Zhang
We give an explicit construction of exact cooperative regenerating codes at the MBCR (minimum bandwidth cooperative regeneration) point. Before the paper, the only known explicit M…
