Regenerating Codes and Locally Recoverable Codes for Distributed Storage Systems
نویسندگان
چکیده
We survey the recent results on applying error control coding to distributed storage systems. In such systems, errors often happen in a burst manner, or maybe only one storage node in the whole distributed system fails. Therefore, only a small amount of information, e.g., one data fragment, has to be recovered. Therefore, accessing the whole data is unnecessary. Especially, we focus on regenerating codes and locally recoverable codes, which reduce the communication cost during repairing of the corrupted data.

Hybrid Regenerating Codes for Distributed Storage Systems
Distributed storage systems are mainly justified due to their ability to store data reliably over some unreliable nodes such that the system can have long term durability. Recently, regenerating codes are proposed to make a balance between the repair bandwidth and the storage capacity per node. This is achieved through using the notion of network coding approach. In this paper, a new variation ...
متن کاملConstruction of optimal locally repairable codes via automorphism groups of rational function fields
Locally repairable codes, or locally recoverable codes (LRC for short) are designed for application in distributed and cloud storage systems. Similar to classical block codes, there is an important bound called the Singleton-type bound for locally repairable codes. In this paper, an optimal locally repairable code refers to a block code achieving this Singleton-type bound. Like classical MDS co...
متن کاملArchitecture-aware Coding for Distributed Storage: Repairable Block Failure Resilient Codes
In large scale distributed storage systems (DSS) deployed in cloud computing, correlated failures resulting in simultaneous failure (or, unavailability) of blocks of nodes are common. In such scenarios, the stored data or a content of a failed node can only be reconstructed from the available live nodes belonging to the available blocks. To analyze the resilience of the system against such bloc...
متن کاملA Practical Study of Exact - BASIC Codes at the MSR Point in Distributed Storage Systems
Regenerating codes have been proven a class of optimal distributed storage codes in the tradeoff between storage capacity and repair bandwidth. However, existing regenerating codes rely on expensive computations such as finite field multiplication. The high coding complexity makes regenerating codes unsuitable for practical distributed storage systems. BASIC codes, standing for Binary Addition ...
متن کاملExact Regenerating Codes for Distributed Storage
Erasure coding techniques are used to increase the reliability of distributed storage systems while minimizing storage overhead. The bandwidth required to repair the system after a node failure also plays a crucial role in the system performance. In [1] authors have shown that a tradeoff exists between storage and repair bandwidth. They also have introduced the scheme of regenerating codes whic...
