Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 14:
15. A communications apparatus, comprising:
a processor configured to detect a first path, wherein the first path is an internal path between two logical management units that carry a virtual network function (VNF),
wherein in response to the first path being faulty, the processor is further configured to detect a second path, wherein the second path is an external path between the two logical management units that carry the VNF,
wherein in response to the second path being normal, the processor is further configured to randomly select, from the two logical management units that carry the VNF, one logical management unit to provide a service to the outside; or
wherein in response to the second path being faulty, the processor is further configured to detect, by using a third-party network element, a path of a first logical management unit of the two logical management units that carry the VNF, and detect, by using the third-party network element, a path of a second logical management unit that carries the VNF, and
wherein the processor is further configured to determine that a logical unit whose path to the third party network element is normal provides the service to the outside.
