Virtual Network Resource Allocation Algorithm Based on Reliability in Large-Scale5G Network Slicing Environment
摘要：In the 5 G network slicing environment, in order to solve the problem of low utilization rate when a large-scale underlying network allocates resources to virtual networks, this paper proposes a virtual network resource allocation algorithm based on reliability in large-scale network environment. First, the reliability of the virtual network is modeled from the importance of the virtual network nodes. Second, the reliability of the underlying network is analyzed from the perspective of the community introverted character and the community relationship value, and the underlying network community division algorithm is proposed. Community reliability and node reliability are analyzed in terms of community and node reliability. Finally, a virtual network resource allocation algorithm based on reliability in large-scale network environment is proposed.In the experimental part, from the two aspects of the underlying network revenue and virtual network mapping success rate, it is verified that the proposed algorithm achieves good results in large-scale virtual network resource allocation.
