Network Coding File System (NCFS)
An emerging application of network coding is to improve the robustness of distributed storage. Recent work has shown that a class of regenerating codes, which are based on the concept of network coding, can improve the data repair throughput when some storage nodes are failed, as compared to the traditional storage schemes such as erasure coding. We have designed and implemented the Network Coding File System (NCFS), a distributed file system that realizes regenerating codes under real network settings. NCFS is a proxy-based file system that transparently stripes data across storage nodes. It adopts a layering design that allows extensibility, so as to provide a platform for exploring implementations of different storage schemes. The system provides a practical and extensible platform for realizing theories of regenerating codes in distributed file systems.
