Method for managing service in network function virtualization architecture, and apparatus

A first network element in a network function virtualization (NFV) architecture, comprising:

• a processing unit, configured to, after receiving a network function virtualization (NFV) resource change notification sent by a virtualized infrastructure manager (VIM), generate first constraint information used to modify at least one of NFVI software and hardware, wherein after receiving the NFV resource change notification sent by the VIM, query, by the first network element, for real-time running status data of a virtualized network function (VNF), and generating second constraint information based on a virtualized network function descriptor VNFD;
• and
• convert, by the first network element, the second constraint information into the first constraint information;
• and
• a transceiver unit, configured to, in coordination with the processing unit, send a first notification message to the VIM, wherein the first notification message carries the first constraint information, and the first constraint information is used by the VIM to modify at least one of NFVI software and hardware based on the first constraint information.

A service management method, wherein the method is applied to a network function virtualization (NFV) architecture, and the method comprises:

• determining, by a first network element, an object affected by a change of a network function virtualization (NFV) resource, wherein the object affected by the change of the NFV resource is a virtualized network function (VNF) instance, a virtualized network function component (VNFC) instance, or a network service NS instance associated with the virtualized network function (VNF) instance, and the NFV resource comprises at least one of the following resources:
• a virtual computing resource, a virtual storage resource, and a virtual network resource, wherein after determining object affected by a change to the NFV resource, querying, by the first network element, for real-time running status data of a virtualized network function (VNF), and generating second constraint information based on a virtualized network function descriptor VNFD;
• converting, by the first network element, the second constraint information into the first constraint information;
• and
• sending, by the first network element to a second network element, a first notification message used to indicate NFV resource maintenance, wherein the first notification message carries identification information of the object affected by the change of the NFV resource, so that the second network element manages a service in the object affected by the change of the NFV resource.
