The Design and Implementation of Random Linear Network Coding Based Distributed Storage System in Dynamic Networks

Nowadays, different end devices with different computation and bandwidth capabilities acquire data from Internet. To improve efficiency of data storage and retrieve, in this paper, we study how to use random linear network coding to construct an efficient distributed storage system to reduce the traffic cost in a dynamic network. In order to balance the success ratio of recovery traffic cost and traffic speed, we firstly introduce a random network coding scheme and implement a practically available distributed storage system in the actual environment. We then adjust different parameters, e.g., finite fields, link bandwidth, node computing capabilities, etc., to evaluate the proposed system. Finally, experiment results show the efficiency of the proposed designs.
