Comprehensive service station virtual network fault diagnosis method and device

Abstract

According to the comprehensive service station virtual network fault diagnosis method and device provided by one or more embodiments of the invention, the fault propagation model is constructed, false fault nodes are firstly removed, and the virtual services are sorted based on the fault risk degree, so that important virtual services are diagnosed preferentially, and for each virtual service, and the interpretation capability of the corresponding suspected fault node to the virtual service is calculated, thereby constructing a fault set, and effectively improving the network fault diagnosis rate.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of virtual network fault diagnosis, and in particular to a virtual network fault diagnosis method and device for an integrated service station. Background technique [0002] Due to the advantages of on-demand expansion and dynamic scheduling, network virtualization technology has gradually become a key technology for efficient network operation in recent years. [0003] When disasters such as fires, floods, mudslides, and earthquakes occur in a certain area, large-scale failures will occur in the network. In this context, for network operators, how to ensure fast recovery of key service failures, thereby ensuring the availability of key services, is an urgent problem to be solved. [0004] In the prior art, existing network fault diagnosis models include a binary dependency fault model, a graphic dependency fault model, a Bayesian dependency matrix model, and the like. [000...
