Embodiment 1
[0093] Based on the above system structure, image 3 It is a schematic flowchart corresponding to the resource application method provided in Embodiment 1 of the present invention. Such as image 3 As shown, the method includes:
[0094] Step 301, the VNF determines the number of resources to be applied for;
[0095] Step 302, the VNF sends a resource application message to the VNFM, and the resource application message is used for the VNFM to apply for resources according to the number of resources to be applied for;
[0096] Step 303, the VNFM receives the resource application message sent by the VNF;
[0097] Step 304, the VNFM applies for resources according to the number of resources to be applied for;
[0098] Step 305, the VNFM sends an application response message to the VNF, and the application response message is a resource application success response or a resource application failure response;
[0099] Step 306, the VNF receives the application response messag...
Embodiment 2
[0120] Figure 5 A schematic flowchart corresponding to the method for creating a VNF instance provided in Embodiment 2 of the present invention, as shown in Figure 5 As shown, the method includes:
[0121] Step 501, the VNF determines the number of resources to be applied for, and generates a VNFD file according to the number of resources to be applied for;
[0122] Step 502, the VNF sends an instance creation message to the VNFM, and the instance creation message is used for the VNFM to create a VNF instance according to the VNFD file;
[0123] Step 503, the VNFM receives the instance creation message sent by the VNF;
[0124] Step 504, VNFM creates a VNF instance according to the VNFD file;
[0125] Step 505, the VNFM sends a creation response message to the VNF, and the creation response message includes the creation result of the VNF instance;
[0126] Step 506, the VNF receives the creation response message returned by the VNFM.
[0127] In the resource application...

Abstract
The invention discloses a resource application method, a VNF instance creation method and a device. The method comprises the following steps: after determining the number of to-be-applied resources, the VNF sends a resource application message to a VNFM, wherein the resource application message is used for the VNFM to perform resource application according to the number of the to-be-applied resources; and the VNF receives a resource application result returned by the VNFM. It can be seen that, in a resource application process in the embodiment of the invention, interaction between the VNF andthe VNFM is introduced, since the VNF can flexibly determine the number of the to-be-applied resources according to resource needs, the resource applied by the VNFM is enabled to flexibly satisfy dynamic variation of the resource needs; moreover, the number of the to-be-applied resources is generated dynamically by the VNF, thus, compared with a mode of artificially preparing a VNFD file in advance in the existing technology, the method provided by the invention is more convenient and practicable.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a resource application and VNF instance creation method and device. Background technique [0002] Traditional telecommunication systems are composed of various dedicated hardware devices, and different applications use different hardware devices. As the network scale grows, the system becomes more and more complex, which brings many challenges, including the development and launch of new services, system operation and maintenance, and resource utilization. In order to meet these challenges and utilize virtualization technology and cloud computing technology in the IT industry, at the "SDN and OpenFlow World Congress" conference held on October 22, 2012, 13 major telecom operators in the world jointly released the network function virtualization Network Functions Virtualization (NFV) white paper, and announced the establishment of NFV ISG in ETSI to formulate the requireme...
