Research on Reliability Measurement Model and Evaluation Method of Distributed Storage Network
Abstract— The structure of distributed storage network is more complex and the number of nodes is increasing. The reliability of the network based on the undirected graph analysis has a certain deviation, because the tasks of each node in the storage network are different, and the upload and download speed is not consistent. Therefore, we introduce the concept of node importance and system entropy and propose a distributed storage network reliability measurement model based on directed graph. Through the calculation comparison, we can see that the reliability evaluation results obtained by this measurement model are closer to the real situation and have great reference value.
Index Terms— distributed storage, network reliability, measurement model, directed graph, node importance, system entropy.
