Abstract
In the 5G network slicing environment, in order to solve the problem of low success rate of virtual network mapping in the existing research, this paper proposes a resource allocation algorithm of power communication network based on reliability and historical data under 5G network slicing. First, the reliability of the virtual network node is analyzed from three aspects: the CPU resources of the virtual node, the connected link resources, and the centrality of the node. The reliability of the underlying network node is analyzed from three aspects: the reliability matrix of the underlying node, the CPU allocation history matrix of the underlying node, and the underlying link allocation history matrix. Secondly, based on the virtual network model and the underlying network model, a resource allocation algorithm of power communication network based on reliability and historical data is proposed. In simulation experiments, it is verified that the algorithm in this paper effectively improves the revenue of the underlying network and the mapping success rate of the virtual network.
