Claim 0:
1. A method, comprising:
obtaining information about a first fault in a first network domain and information about a second fault in a second network domain, wherein the information about the first fault comprises a first time of the first fault and first service information of the first fault, and the information about the second fault comprises a second time of the second fault and second service information of the second fault;
determining a time correlation based on the first time and the second time, wherein the time correlation is that the first time and the second time meet a time constraint condition;
determining a service information correlation based on the first service information and the second service information, wherein the service information correlation is that the first service information and the second service information meet a service information constraint condition; and
determining, based on the time correlation and the service information correlation, that the first fault in the first network domain and the second fault in the second network domain are caused by a same fault.
