Embodiment 1

[0110] Figure 9 is the process of managing virtual resources after VNF instantiation according to an optional embodiment of the present invention Figure 1 ,Such as Figure 9 As shown, the process includes the following methods:

[0111] 1) The VNFM sends the virtual resources of the VNF and the information on the completion of the VNF instantiation to the EM; the virtual resource information includes the ID of the virtual machine, the number of the virtual machines, the specification parameters of each virtual machine, and the size of each virtual machine, where the virtual machine The specification parameters include at least the memory capacity, the number of CPUs, and the storage capacity. It may also include the identification and VNFC type of each virtual network function component VNFC implemented by the virtual machine.

[0112] 2) The EM determines and executes the configuration operation of the management object used to manage the VNF and its virtual resources ac...

Embodiment 2

[0115] Figure 10 is the process of managing virtual resources after VNF instantiation according to an optional embodiment of the present invention Figure II ,Such as Figure 10 As shown, the process can include the following methods:

[0116] 1) If the VNFM executes the resource allocation in the instantiated VNF, then the VNFM sends the virtual resources of the VNF and the instantiated VNF to the NFVO; if the NFVO executes the resource allocation in the instantiated VNF, it directly enters 2);

[0117] 2) NFVO sends the virtual resources of the virtual network function VNF and the information on the completion of the instantiated VNF to the NM; the virtual resource information includes the ID of each virtual machine, the number of virtual machines, the specification parameters of each virtual machine, and the size of each virtual machine , the specifications include at least the memory capacity, the number of CPUs, and the storage capacity. It may also include the identi...

Embodiment 3

[0124] Figure 11 It is the process of managing virtual resources after VNF expansion according to an optional embodiment of the present invention Figure 1 ,Such as Figure 11 As shown, the process includes:

[0125] 1) The VNFM sends the virtual resource of the VNF and the completion information of the scaled out VNF ​​to the EM; the virtual resource information includes the ID of the newly added virtual machine, the number of the newly added virtual machines, the specification parameters of each newly added virtual machine, Specifications of each newly added virtual machine, specification parameters include at least memory capacity, number of CPUs, and storage capacity. It may also include the identification and VNFC type of the virtual network function component VNFC implemented by each virtual machine.

[0126] 2) The EM determines and executes the configuration operation of the management object used to manage the VNF and its virtual resources according to the receive...

Abstract

The invention provides a method and a device for managing virtual resources of a VNF (Virtualised Network Function). The method comprises the following steps: EM (Element Management) receives virtual resource information of the VNF which is sent by a VNFM (VNF Manager), and information of a completed life cycle operation of the VNF, or receives a configuration message of a management object for managing the VNF and the virtual resources of the VNF, wherein the configuration message is sent by NM (Network Management); and according to the virtual resource information of the VNF and the information of the completed life cycle operation of the VNF, or according to the configuration message of the management object for managing the VNF and the virtual resources of the VNF, the EM determines and executes a configuration operation of the management object for managing the VNF and the virtual resources of the VNF. By the method and the device which are provided by the invention, the problem that in the related technologies, the NM and the EM cannot implement dynamic management on the VNF is solved, and the blank of related technologies is filled.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for managing virtual resources of a virtual network function (VNF). Background technique [0002] In the existing network architecture, network functions and network devices are in a super-coupling relationship, and network functions are implemented through specially designed, vendor-specific devices. This has brought many inconveniences: for example, the performance improvement of these devices is limited by the development of hardware that meets specific / customized requirements while maintaining carrier-level reliability; another example, when operators want to deploy new services, Newly designed equipment with related special functions must be deployed in advance, which will increase the service deployment cost of operators. On the other hand, with the rapid improvement of CPU and memory performance, the basic conditions for running network functions in ...
