“…In the data layer of SDN, these six kinds of technology data are different data sets, and each kind of data domain is oriented to a certain kind of data business. When the data required for a business are derived from a number of different data sets, there needs to be a more regional virtual entity data set into a virtual data to support this business field [21][22][23] ; this can easily integrate physical data set area data and provide the corresponding data resources to support this business. Under the framework of SDN, this article discusses how to set up virtual data domain problems in the virtual cube market based on business requests.…”

Currently, large data sets are deployed on large-scale clusters, which require a large amount of physical resources. However, current network architecture does not have flexible deployment, making it difficult to adjust physical resources after deployment. Based on software definition network, this article proposes a framework for building virtual data domain, which establishes a multi-attribute decision model by network nodes for optimizing the deployment of control layer, so as to realize large-scale deployment. By analyzing the actual usage and virtual distribution of the underlying data resources, a mapping algorithm of network resource overhead-allocation ratio is proposed for adjusting the mapping space of network flow based on the mapping result, so as to meet more virtual domain applications. At the same time, the reasonable utilization of resources is helpful to reduce the communication delay in domain. Simulation results show that compared with the shortest path mapping and greedy resource mapping algorithms, the virtual domain established by the network resource overhead-allocation algorithm can improve the resource utilization rate by 10% and reduce the intra-domain communication delay by 30%. Therefore, under the background of the expanding scale of data domain, this framework can solve the problem that the current backward network architecture cannot adapt to the development trend of the information field.
