Embodiment Construction

[0074] Wherein, the resource authorization request may be sent by the virtualized network function manager VNFM or other components.

[0075] Specifically, the file information includes: the virtual machine image file or the resource address of the virtual machine image file;

[0077] Step 1041, when the target virtualization resource manager exists in the data center, virtualize the target

[0078] Step 1042, when the target virtualization resource manager does not exist in the data center, the virtual machine

[0082] According to the second identification, inquire whether there is in the transmission record information of the virtual machine image file

[0083] Here, the identity of the VIM is used to uniquely identify the VIM in the system, and the virtualized resource manager logo can be used.

[0090] Integrity and legitimacy checks are performed on the virtual network function description file uploaded by the administrator;

[0092] After sending the virtual network function...

Abstract

The invention provides a virtual network function instantiation method and a network function virtualization orchestrator, which relate to the technical field of communication. The method includes: receiving a resource authorization request; determining a candidate virtualization resource manager according to the resource authorization request, and the candidate virtualization resource manager is used to allocate virtual resources to the virtual network function when deploying the virtual network function; querying the Whether there is a target virtualization resource manager in the data center to which the candidate virtualization resource manager belongs, and the target virtualization resource manager has loaded a virtual machine image file; according to the query result, send the corresponding file information to the candidate Virtualization resource manager. The solution of the present invention solves the problem of being unable to support the sharing requirements for image files belonging to multiple virtualization resource managers in the same data center.

Description

Method for virtual network function instantiation and network function virtualization orchestrator technical field The present invention relates to the technical field of communication, particularly refers to a kind of method and network function of virtual network function instantiation Virtualization Orchestrator. Background technique The network element of the existing traditional basic communication network adopts software / hardware vertical integration architecture, which restricts cloud computing to In order to meet the needs of flexible and dynamic allocation of network resources, efficient use of resources, and fair resource allocation. therefore, NFV (Network Function Virtualization, network function virtualization) technology is proposed. The core idea of ​​NFV technology is to put logic The network functions on the VNF are decoupled from the physical hardware devices, which are mainly composed of three parts: VNF (Virtualized Network Function, virtual...
