A method and apparatus of managing VNF instantiation

Abstract

The present application provides a method of managing VNF instantiation, the method comprising: a requesting device carrying instance information of a virtualized network function VNF in the NS to beinstantiated by a second device in a request for instantiating an NS to a first device. After receiving the request to instantiate the NS, the first device determines the VNF in the NS to be instantiated by the second device, and records the instance identification of the VNF to be instantiated by the second device. In a phase where the VNF is instantiated, the first device authorizes the instantiation of the VNF according to an instance identification of the VNF recorded in the NS instantiation process. By carrying the instance ID of the VNF instantiated by the second device in a request to the instantiated NS sent to the first device, the first device can be informed of the relationship between the VNF instantiated by the second device and the NS, so that the instantiation of the VNF canbe controlled according to the relationship to ensure that the second device instantiates an effective VNF and avoid waste of resources.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a method and device for managing VNF instantiation. Background technique [0002] Network Function Virtualization (English: Network Function Virtualization, NFV for short), refers to the use of general-purpose hardware devices and virtualization technology to carry the functions of special devices in traditional networks, thereby reducing the expensive cost of deploying special devices. The software is not tied to proprietary hardware, so that device functions are no longer dependent on specialized hardware. Compared with traditional networks, NFV introduces a virtualization layer, through network management and orchestration, to realize the lifecycle management of virtualized network functions (Virtualized Network Function, VNF) and virtualized network services (Network Service, NS). In the NFV architecture, VNF is the lower-layer network function, and NS is the...

AI Technical Summary

Problems solved by technology

[0005] In the solution of instantiating VNF through EM, because EM has no relevant information about NS, it cannot associate VNF with NS during the process of instantiating VNF, which makes the VNF instantiated by EM unable to provide external services, because VNF is just a virtualized network function that constitutes NS. Only NS can provide specific network services. VNFs independent of NS cannot provide external services independently.

If EM instantiates a large number of VNFs independent of NS, it will inevitably cause waste of resources
