5G Slice Allocation Algorithm Based on Mapping Relation

In the 5G network slicing environment, in order to improve the utilization of underlying network resources, this paper proposes a resource allocation algorithm of power communication network based on mapping relation under 5G network slicing. The successful virtual network resource allocation case is modeled as a knowledge underlying to provide data support for the new virtual network resource allocation problem. According to the topology characteristics of the virtual network, the importance of the virtual node is analyzed to determine the priority of the virtual node when the virtual network resource is allocated. In the experimental part, it is verified that the algorithm in this paper has achieved good results in terms of virtual network mapping success rate and underlying network resource utilization.
