A Survey on CloudNCFS: Building Network-Coding-Based Distributed Storage System
Pranjali A. Pali | N. D. Kale 
Abstract: NCCloud is a proof of concept prototype of a network coding based file system that aims at providing fault tolerance and reducing data repair cost when storing files using multiple cloud storage. NCCloud is a proxy based file system that interconnect multiple (cloud) storage nodes. It can be mounted as a directory on Linux, and file uploading/downloading are done by copying files to/ from the mounted directory. NCCloud is built on FUSE, an open source programmable user space file system that provides application programmable interface (APIs) for file system operations. From the point of view of user application, NCCloud present a file system network codes for storage repair require that storage nodes encode the stored data during the repair process. However, this may not be feasible for some storage systems where nodes only provide the basic I/O functionalities but do not have the encoding capability. work is to adapt the benefits of network codes in the storage repair of a practical storage setting, by relaxing the encoding requirement of storage nodes. Yet that transparently stripes data across storage NCCloud support variety of coding schemes, in particular the functional minimum storage generating (F-MSR) code. Compared to traditional optimal erasure codes, FMSR codes maintains the same storage overhead under the same data redundancy level, but uses less repair traffic during the recovery of a single failed node. NCCloud realizes regenerating codes in a practical cloud storage system that does not require any encoding/decoding intelligence on the cloud storage nodes.
