Problems solved by technology

The VNF registration and instantiation scheme in the existing specifications is complex and the system is not easy to use
Moreover, generally, when manufacturers release VNF version packages, they will not release different version packages for different capacities.
In other words, according to the current ETSI specification, VNF instantiation cannot be realized in this case

Embodiment Construction

[0105] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0106] Figure 5 A flow chart of the method for realizing VNF instantiation for the present invention, such as Figure 5 shown, including:

[0107] Step 501: During the VNF instantiation process, the VNFM calculates the VNFC and its VDUs of the VNF instantiation according to the tool for automatically calculating the VDU, combined with the capacity to be instantiated and its information.

[0108] This step specifically includes:

[0109] When the VNF that is responsible for allocating resources by the NFVO is instantiated, when the NFVO requests the VNFM to instantiate the...

Abstract

The invention discloses a method and system for realizing VNF instantiation, as well as NFVO and VNFM, including that in the process of VNF instantiation, VNFM automatically calculates the VNF according to the tool for automatically calculating VDU, combined with the capacity to be instantiated and its information Instantiated VNFC and its VDUs. In the VNF instantiation process of the present invention, on the basis of the original instantiation mechanism, there is no need to release different VNF ​​version packages for different capacities, which reduces the number of times VNF releases version packages, reduces the number of VNF versions managed by NFVO, and simplifies The VNF instantiation process is simplified, thereby providing ease of use for VNF management. The technical solution provided by the invention is applicable to all types of VNFs.

Description

technical field [0001] The present invention relates to network function virtualization (NFV, Network Functions Virtualization) technology, especially a method and system for realizing VNF instantiation, NFVO and VNFM. Background technique [0002] NFV technology refers to the integration of traditional network functions, such as: Proxy call session control function entity (P-CSCF, Proxy call session control Function), inquiry call session control function entity (I-CSCF, Interrogating call session control function), service The call session control function entity (S-CSCF, Serving call session control Function), the home subscriber server (HSS, Home subscriberServer), and the application server (AS, Application Server), etc. are virtualized, and these virtual network function components ( VNFC, Virtualized Network Function Component) is deployed on cloud virtual machines to realize the virtualization of network functions. The virtualized network function is called virtual n...
