Robust distributed storage based on fountain codes
Aiqing Zhang · Engineering Journal of Wuhan University · 2007
A kind of robust distributed data storage technology is investigated;and it can ensure the reliable storage and efficient restore of data. Fountain codes and their improved codes, namely, LT codes and Raptor codes, are utilized in the distributed network storage; and conclusion is arrived that in order to restore M data packets, we need only a little more than M packets in the user end. This method can endure some packet loss, thus the robustness and efficiency of data storage are realized. The key factors that affect the storage of data are discussed finally.
