Integrated Energy Virtual Network Service Fault Diagnosis Algorithm Under Disaster Event Environment

When a disaster occurs, how to improve the accuracy of integrated energy virtual network service fault diagnosis algorithm is a key issue that needs to be solved urgently. To solve this problem, this paper proposes a fault diagnosis algorithm for integrated energy virtual network services in a disaster event environment. Based on the risk of failure, the algorithm first diagnoses the virtual network service with the highest failure probability. By setting the fault threshold, many underlying links in the fault propagation model are streamlined. When locating the fault of the virtual network service, the total fault risk of the virtual network service is proposed, and the performance of the fault diagnosis algorithm is improved based on this. Through experiments, the performance of the algorithm is analyzed from the three dimensions of the accuracy of the fault diagnosis algorithm, the false alarm rate and the diagnosis time, and it is verified that the algorithm in this paper improves the performance of the fault diagnosis algorithm.
