RNCDDS (Random Network Coded Distributed Data System)

Many Random Network Coding based storage systems have been proposed to increase robustness in terms of data preservation and storage efficiency. However, there are two major practical issues: (1) slow encoding and decoding speeds and (2) difficult access to the data. In this paper, RNCDDS solves problem (1) by introducing a new and efficient Galois Field arithmetic library and problem (2) by employing a new JavaScript program. As a result, RNCDDS is not only theoretically more robust and storage efficient than major distributed data systems such as Hadoop (HDFS) and GlusterFS, but also outperforms them in all speed measurements. Also, the proposed JavaScript program enables easy data fetch through a web browser including watching a video with an HTML5 video player and has potential for drastically reducing data storage amount in a cloud system or Content Delivery Network.

gf-nishida-16

gf-nishida-16 is an efficient 16bit Galois field arithmetic library that is open source and outperforms other open source Galois field arithmetic libraries in processing speed. gf-nishida-16 is the core of RNCDDS and plays the most important role in its fast encoding and decoding. Please see our technical paper "gf-nishida-16: Simple and Efficient GF(216) Arithmetic Library" for further details.
