Problems solved by technology

[0004] At present, although the ETSI (European Telecommunications Standards Institute, European Telecommunications Standards Institute) specification defines the auto-scaling field auto_scale_policy in the VNFD (Virtual Network Function Descriptor, virtualized network function descriptor), it lacks a variety of how to implement VNF ​​scaling actions. The description of centralized management and unified triggering cannot complete the rapid deployment and flexible adjustment of VNF instances according to business needs

Embodiment 1

[0047] Such as figure 2 As shown, a virtualized network application functional unit VNF ​​scaling management method, the method comprising:

[0048] Step S10: configuring a scaling solution for the VNF instance;

[0049] Step S12: Bind the predefined business scenario event with the scaling solution;

[0050] Step S13: When a predefined business scenario event occurs, execute the scaling solution bound to the business scenario event.

[0051] Optionally, step S11 can be implemented in the following manner:

[0052] First configure a deployment specification for the VNF instance; then configure a scaling solution for the VNF instance according to the deployment specification.

[0053] Optionally,

[0054] In this embodiment, the number of deployment specifications configured by the VNF instance is two or more; the number of scaling schemes configured by the VNF instance is one or more.

[0055] Optionally, in step S12, a predefined business scenario event is bound to one ...

Embodiment 2

[0064] The technical solution of the present application is further described below.

[0065] In this embodiment, different deployment specifications and scaling solutions can be defined for VNF instances according to different scenarios. A scaling solution can contain one scaling action or multiple scaling actions (including horizontal and vertical latitudes), and can define scaling actions in one latitude or multiple latitudes.

[0066]Define scenario events according to business requirements, and bind different scaling solutions.

[0067] Through real-time monitoring of some key parameters of the business (such as the number of registered users), the scaling requirements of the business are known, scene events are generated according to the scaling requirements, the corresponding bound scaling solutions are triggered, and the planned scaling actions are executed.

[0068] The configuration scheme of the VNF instance scaling scheme in this embodiment is mainly carried out f...

example 1

[0076] If three deployment specifications F1, F2, and F3 are defined in the VNF template. The scaling scheme of a VNF instance can be defined as follows:

[0077] Scaling solution P1: switch from deployment specification F1 to deployment specification F2;

[0078] Scaling solution P2: switch from deployment specification F2 to deployment specification F3;

[0079] Scaling solution P3: switch from deployment specification F3 to deployment specification F1;

[0080] Each scaling scheme in the above configuration scheme defines a scaling action. In other configuration schemes, a scaling scheme can also define multiple scaling actions.

[0081] 3. Define business scenario events

[0082] When the business changes, define a business scenario event, which can be used as a trigger event for the VNF instance scaling solution.

[0083] Business data (such as the number of registered users) can be collected regularly, business requirements can be determined based on the collected i...

Abstract

The invention relates to a scalable VNF (Virtual Network Feature) management method. The method comprises the steps of: configuring a scaling scheme for a VNF example; binding a pre-defined service scene event to the scaling scheme; and, when the pre-defined service scene event occurs, executing the scaling scheme bond to the service scene event. By means of the technical scheme, the service scene event is bond to the VNF scaling scheme; therefore, diversified management and unified triggering of VNF scaling actions can be realized; and thus, rapid deployment and flexible adjustment of VNF examples are completed according to service requirements.

Description

technical field [0001] The present invention relates to the field of NFV (Network Function Virtualization, network function virtualization), in particular to a configuration method and system. Background technique [0002] In order to effectively utilize system resources and reduce operating costs, such as figure 1 As shown, users often deploy multiple VNF (Virtual Network Feature, virtualized network application function unit) instances on the same physical resource, and each VNF instance defines multiple deployment specifications. According to business changes, VNF instances need to flexibly scale between different deployment specifications; conversion between different deployment specifications often requires defining different scaling actions. Scaling actions are divided into two latitudes: horizontal and vertical. Horizontal scaling is performed by adding or reducing the number of virtual units themselves, and vertical scaling is performed by increasing or decreasing t...
