Abstract
The present application provides a method for upgrading a virtualized network function and a network function virtualization orchestrator NFVO. The NFVO includes: a receiver, configured to receive an upgrade request message, the upgrade request message is configured to request the NFVO to upgrade a first software version corresponding to a first VNF to a second software version, the first software version corresponds to a first VNF instance, and the second software version corresponds to a second VNF instance; and a processor, configured to: instantiate the first VNF to obtain the second VNF instance; configure forwarding paths of service flows in an NS, so that a first service flow is forwarded to the first VNF instance and that a second service flow is forwarded to the second VNF instance; and terminate the first VNF instance if it is determined that the first VNF instance runs without loads within a preset time.
