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...
