Patent ID: 11301284

Abstract:
A method for managing virtualized network function (VNF) instantiation, including a first device receiving, from a requester device, a request for instantiating the NS, wherein the request carries instance information of a VNF that is in a network service (NS) and to be instantiated using a second device. After receiving the request, the first device records an instance identifier (ID) of the VNF. In a VNF instantiation phase, the first device authorizes instantiation of the VNF based on the instance ID of the VNF that is recorded during instantiation of the NS. The instance ID of the VNF to be instantiated by the second device is carried in the request, such that the first device can obtain a relationship between the VNF to be instantiated by the second device and the NS, and therefore can control instantiation of the VNF based on the relationship.
