3rd embodiment:
In the present embodiment, in the system of embodiment as shown in Figure 3, NFVO is in VNF instantiation process, according to one VNFM group of the VNFM type selecting can being managed in VNF service template, each VNFM group one Network Load Balance device of configuration, the VNFM in VNFM group is provided reverse proxy function services by this load equalizer；NFVO determines whether to newly-increased VNFM in VNFM group according to the operating capability of VNFM in VNFM group and current loads, if it is desired, then create the empty machine of VNFM according to VNFM service template, and VNFM adds VNFM group.VNFM void machine mirror image comprises the application software of VNFM；NFVO, when receiving VNF example and terminating request, judges whether to need to delete certain VNFM according to the operating capability of VNFM in VNFM group and current loads thereof, if it is desired, then delete empty machine corresponding to VNFM；Namely VNFM is based on the stateless service of REST principle, and therefore it can independently be disposed physically as a functional unit, it is also possible to dispose with EMS, NFVO unification.
Now it is described in detail for the application scenarios of VNF instantiation；As shown in Figure 4, in the present embodiment, virtual network function management method provided by the invention comprises the following steps:
S401:NFVO calls the REST interface of VNF and initiates VNF instantiation request, and this request load equalizer is distributed to a VNFM, this VNFM be responsible for the instantiation process of VNF；
The REST interface of S402:VNFM returns the characterization parameters such as the injection file needed for establishment VNF void machine and floatIP；
S403:NFVO is based on the service template (such as empty machine specification, mirror image etc.) of VNF, and the return call by result VIM interface in conjunction with VNFM creates empty machine, to ensure that NFVO can't see each VNF difference in instantiation process；
S404: if not comprising application software in the mirror image of VNF, VNFM also needs to complete the deployment of VNF application software in VNF instantiation process；
In this case, can a resident installation agent in the mirror image of the OMU of VNF (a corresponding VDU), this installation agent starts backward VNFM with empty machine and initiates REST request (VNF is it is seen that load equalizer, it is not certain specific VNFM), obtain the characterisitic parameter required for software installation and configuration script；
S405:VNF calls the REST interface of VNFM and reports installation progress；
VNFM using the installation progress of VNF as resource conservation, and provide REST interface for NFVO inquiry；
S406:NFVO timing is called the REST interface of VNFM and is obtained installation progress；
In certain embodiments, the elastic telescopic of VNF is also based on the REST interface of VNFM, NFVO and VNFM worked in coordination with.
In summary, by the enforcement of the present invention, at least there is following beneficial effect:
By configuring REST interface for VNFM, make the VNFM can based on REST principle construction web formula Distributed Application, and owing to web is loose coupling and telescopic, so in the virtual network adopting this VNFM and virtual network function management system, the connection of VNFM and other network equipments (such as VNF etc.) is also loose coupling, namely VNFM can flexible deployment, and support elastic telescopic.
Below it is only the specific embodiment of the present invention; not the present invention is done any pro forma restriction; every any simple modification, equivalent variations, combination or modification embodiment of above done according to the technical spirit of the present invention, all still falls within the protection domain of technical solution of the present invention.
