Problems solved by technology

[0004] However, in the instantiation process of virtualized network elements in the existing NFV environment, when assembling each VNFC, it only considers meeting the requirements of a single VNFC at this moment, and assembles it to the computing node without overall planning and global view. As a result, the virtual machines are unevenly distributed among the computing nodes, resulting in a large number of resource fragments and low resource utilization

Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0026] In the following description, the use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating the description of the present application and has no specific meaning by itself. Therefore, 'module', 'part' or 'unit' may be used in combination.

[0027] In related technologies, the VNF instantiation requires the VNFM to parse the VNFD entry to obtain the requirements of each VNFC. Usually, the instantiation of VNF includes direct mode and indirect mode. In direct mode, VNFM reserves relevant resources to t...

Abstract

The embodiment of the invention discloses a VNF instantiation method and device, equipment and a storage medium, and the method comprises the steps: obtaining a VNF resource set according to the resource demand conditions of a VNFM, and enabling the VNF resource set to comprise the state parameters of at least two VNFCs; according to the state parameters of the at least two VNFCs, generating a virtual machine pre-deployment diagram according to a preset algorithm; and deploying virtual machines corresponding to at least two VNFs in the VNF resource set according to a virtual machine pre-deployment graph, so as to implement functions corresponding to the virtual machines after the virtual machines are deployed.

Description

technical field [0001] The embodiment of the present application relates to the field of virtual technology, and relates to but not limited to a VNF instantiation method, device, device and storage medium. Background technique [0002] In a network function virtualization (Network Function Virtualization, NFV) environment, after the virtualization cloud platform is installed and integrated, it has the conditions to instantiate a virtualized network function (Virtualized Network Function, VNF) network element. [0003] In the existing European Telecommunications Standards Institute NFV (European Telecommunication Standards Institute, ETSI NFV) architecture, the instantiation of VNF requires a virtualized network function manager (Virtualized Network Function Manager, VNFM) to parse the virtualized network function descriptor (Virtualized NetworkFunction Descriptor, VNFD) entry to obtain the requirements of each virtualized network function module component (Virtualized Networ...
