Fault Management Platform based on Knowledge Graph in Network Slicing Environment

Abstract

In the network slicing environment, SDN and NFV technologies improve the utilization of network resources. However, these technologies lead to the greater dynamic nature of network resources and bring greater challenges to network fault management. Firstly, based on the analysis of network elements in network slicing environment, the fault management platform architecture in network slicing environment is proposed. Secondly, in order to improve the efficiency of the fault management mechanism, the knowledge graph is applied to the fault management field and the fault management knowledge graph is constructed. The functions that the knowledge framework can realize include fault prediction, elastic strategy, fault location, and fault self-healing. Finally, according to the requirements of fault management, a fault management question answering system based on knowledge graph is designed. From the two dimensions of business feasibility and implementation feasibility, the feasibility of the fault management platform is verified.
