Title: METHOD FOR MIGRATING PHYSICAL NETWORK FUNCTION (PNF) AND RELATED DEVICE
Abstract:
Disclosed in the embodiments of the present invention are a method for migrating a physical network function (PNF) and a related device. The method is applied in a network function virtualization (NFV) system, and the NFV system comprises a network function virtualization orchestrator (NFVO). The method comprises: the NFVO receiving a triggering and migration message sent by a network management system (OSS), to trigger the NFVO to migrate the function of a PNF node to the NFV system, the NSD having a virtualized network resource descriptor for replacing the PNF; after the NFV deletes the PNF resource configuration of the NFV, the NFVO instantiating the virtualized network resource of the PNF on the basis of the PNFD identifier, the instantiated identifier of the PNF node and the virtualized network resource descriptor . Therefore, rapid migration of the PNF function onto the VNF system can be achieved, and the time for migrating the PNF to the VNF is shortened.
