Abstract
Embodiments of the present invention provide a scale-out association method and apparatus, so as to implement a scale-out association operation between VNFs. After initiating a scale-out, a first VNF sends a scale-out notification message to a second VNF that is directly associated with the first VNF. The scale-out notification message of the first VNF carries a scale-out magnitude parameter of the first VNF. The second VNF determines, according to the scale-out magnitude parameter of the first VNF and a service processing capability of the second VNF, whether the second VNF needs to be scaled out. If it is determined the second VNF needs to be scaled out, then the second VNF sends a scale-out request message to a VNFM.

A scale-out association method, comprising:
- receiving, by a second virtualized network function (VNF), a scale-out notification message of a first VNF sent by the first VNF after the first VNF initiated a scale-out operation, wherein the scale-out notification message of the first VNF carries a scale-out magnitude parameter of the first VNF, the scale-out magnitude parameter of the first VNF indicates a service capacity of the first VNF after the first VNF is scaled out and is used by the second VNF to determine whether the second VNF is to be scaled out, and the first VNF is directly associated with the second VNF which means data flow between the first VNF and the second VNF without transiting through another VNF;
- determining, by the second VNF, whether a service processing capability of the second VNF satisfies the scale-out magnitude parameter of the first VNF;
- if the service processing capability of the second VNF satisfies the scale-out magnitude parameter of the first VNF, determining, by the second VNF, that the second VNF does not need to be scaled out;
- and
- if the service processing capability of the second VNF does not satisfy the scale-out magnitude parameter of the first VNF, determining, by the second VNF, that the second VNF is to be scaled out;
- and
- sending, by the second VNF, a scale-out request message to a virtualized network function manager (VNFM) to request to scale out the second VNF.
A scale-out association apparatus, comprising:
- a processor, configured to receive a scale-out notification message of a first virtualized network function (VNF) sent by the first VNF after the first VNF initiated a scale-out operation, wherein the scale-out notification message of the first VNF carries a scale-out magnitude parameter of the first VNF, the scale-out magnitude parameter of the first VNF indicates a service capacity of the first VNF after the first VNF is scaled out and is used by the processor to determine whether a second VNF is to be scaled out, and the first VNF is directly associated with the second VNF which means data flow between the first VNF and the second VNF without transiting through another VNF, wherein
- the processor is further configured to:
- determine whether a service processing capability of the second VNF satisfies the scale-out magnitude parameter of the first VNF,
- if the service processing capability of the second VNF satisfies the scale-out magnitude parameter of the first VNF, determine that the second VNF does not need to be scaled out;
- and
- if the service processing capability of the second VNF does not satisfy the scale-out magnitude parameter of the first VNF, determine that the second VNF is to be scaled out, and
- send a scale-out request message to a virtualized network function manager (VNFM), wherein the scale-out request message is used to request to scale out the second VNF.
