METHOD FOR UPGRADING VIRTUALIZED NETWORK FUNCTION AND NETWORK FUNCTION VIRTUALIZATION ORCHESTRATOR

摘要

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.

1. A network function virtualization orchestrator, comprising:
a receiver, configured to receive an upgrade request message sent by a sender, wherein the upgrade request message is configured to request the network function virtualization orchestrator (NFVO) to upgrade a first software version corresponding to a first virtualized network function (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 according to a preset virtualized network function descriptor (VNFD) of the second software version of the first VNF in a VNF catalog to obtain the second VNF instance; after connecting the second VNF instance to a network service (NS) in which the first VNF instance is located, configure forwarding paths of service flows in the NS, so that a first service flow is forwarded to the first VNF instance for processing and that a second service flow is forwarded to the second VNF instance for processing; and terminate, the first VNF instance if it is determined that the first VNF instance runs without loads within a preset time.
