Virtual Network Resource Allocation Algorithm Based on Reliability and Distribution Strategy Under Network Slicing

Abstract

AbstractIn the network slicing environment, how to improve the reliability of virtual network resources is an important research content. To solve this problem, this paper proposes a virtual network resource allocation algorithm based on reliability and distribution strategy. The algorithm includes three steps: network reliability evaluation, virtual node resource allocation, and virtual link resource allocation. When virtual node resources are allocated, the algorithm allocates high-reliability bottom nodes to virtual nodes. In the allocation of virtual link resources, the algorithm allocates high-reliability bottom paths for virtual links, and uses shunting technology to further improve the reliability of virtual links. The experimental part verifies that under different network scales and network reliability environments, the algorithm of this paper improves the reliability of virtual network resources.KeywordsNetwork slicingUnderlying networkVirtual networkResource allocationReliability
