Optimistic Erasure-Coded Distributed Storage
We study erasure-coded atomic register implementations in an asynchronous crash-recovery model. Erasure coding provides a cheap and space-efficient way to tolerate failures in a distributed system. This paper presents ORCAS, Optimistic eRasure-Coded Atomic Storage, which consists of two separate implementations, ORCAS-A and ORCAS-B. In terms of storage space used, ORCAS-A is more efficient in s...
متن کاملA Layered Architecture for Erasure-Coded Consistent Distributed Storage
Motivated by emerging applications to the edge computing paradigm, we introduce a two-layer erasure-coded fault-tolerant distributed storage system offering atomic access for read and write operations. In edge computing, clients interact with an edge-layer of servers that is geographically near; the edge-layer in turn interacts with a back-end layer of servers. The edge-layer provides low laten...
متن کاملErasure Coding in Distributed Storage Systems
Data centers are nowadays highly distributed, possibly over continents, to cope with the huge amounts of data collected these days. To deal with data loss in an environment where hardware failures are very common, researchers have developed new kinds of erasure codes. Erasure coding is a common technique used in all sorts of digital communication, including deep space communication and QR-codes...
متن کاملOn Erasure Coding for Distributed Storage and Streaming Communications
The work presented in this thesis revolves around erasure correction coding, as applied to distributed data storage and real-time streaming communications. First, we examine the problem of allocating a given storage budget over a set of nodes for maximum reliability. The objective is to find an allocation of the budget that maximizes the probability of successful recovery by a data collector ac...
متن کاملLink-Adaptive Distributed Coding for Multisource Cooperation
Combining multisource cooperation and link-adaptive regenerative techniques, a novel protocol is developed capable of achieving diversity order up to the number of cooperating users and large coding gains. The approach relies on a two-phase protocol. In Phase 1, cooperating sources exchange information-bearing blocks, while in Phase 2, they transmit reencoded versions of the original blocks. Di...
