## Abstract

An embodiment of the present invention provides a NFV based fault processing method. The method includes: determining a NFVI fault; obtaining self-healing policy information used to indicate whether to perform a self-healing operation on the NFVI fault; and performing the self-healing operation on the NFVI fault when the self-healing policy information indicates that the self-healing operation is to be performed on the NFVI fault. Therefore, time for reporting and making a fault analysis for the infrastructure fault can be saved, the infrastructure fault is rectified as quickly as possible, a fault processing delay is reduced, and system performance can be improved.

## Claims
