Fault recovery method and apparatus, and storage medium

An apparatus, comprising:

• at least one processor;
• and
• at least one memory, coupled to the at least one processor and configured to store instructions that when executed by the at least one processor cause the apparatus to:
• obtain network composition information and abnormal event information of a target network, wherein the network composition information comprises a network topology of the target network and device information of a plurality of network devices on the target network, and the device information comprises one or more of interface configuration information, protocol configuration information, and service configuration information;
• determine a possible root cause of a fault of the target network based on the network composition information and the abnormal event information;
• determine at least one fault recovery plan based on the possible root cause;
• determine, according to the network composition information or according to the network composition information and the possible root cause, impact on service performance after any fault recovery plan from the at least one fault recovery plan is implemented;
• and
• select, based on the impact on service performance and from the at least one fault recovery plan, a fault recovery plan for network fault recovery.

An apparatus comprising:

• at least one processor;
• and
• at least one memory, coupled to the at least one processor and configured to store instructions that when executed by the at least one processor cause the apparatus to:
• receive a possible root cause, sent by an analysis device, of a fault of a target network, wherein the possible root cause of the fault is determined by the analysis device based on network composition information and abnormal event information, the network composition information comprises a network topology of the target network and device information of a plurality of network devices on the target network, and the device information comprises one or more of interface configuration information, protocol configuration information, and service configuration information;
• determine at least one fault recovery plan based on the possible root cause;
• determine, according to the network composition information or according to the network composition information and the possible root cause, impact on service performance after any fault recovery plan from the at least one fault recovery plan is implemented;
• and
• select, based on the impact on service performance and from the at least one fault recovery plan, a fault recovery plan for network fault recovery.
