The openstack virtual machine deployment algorithm is mainly from the perspective of IT, and mainly arranges and monitors the balance of hardware resource usage. It does not consider virtual machine deployment from the perspective of VNF, nor does it consider the security of VNF.
Considering the virtual machine deployment only from the perspective of hardware resources, it may cause the virtual machines of the same VNF to be deployed on the same server, or important virtual machines to be deployed on the same server, causing the entire VNF to fail when the server is down
In order to prevent all virtual machines of the VNF from being deployed on the same server, if all virtual machines are set to be single and mutually exclusive, then for virtual machines with N+1 disaster recovery relationship, the number of virtual machines may be greater than the number of hardware servers. Cause virtual machine deployment to fail

Embodiment Construction
[0049] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0050] Such as image 3As shown, the embodiment of the present invention provides a method for balanced deployment of virtual network functions, and the method includes the following steps:
[0051] S1: Obtain the resource information of each server and the function information of each virtual machine to be deployed in the VNF (Virtual Network Function);
[0052] It should be noted that, in the embodiment of the present invention, virtual machine deployment of VNF can be completed by VIM (Virtualization Infrastructure Manager) and VNFM (Virtual Network Function Manager) in MANO (Management Orchestration Domain) of NFV. Specifically, the VIM interface and the VNFM interface can be used as deployment components. Through the VIM interface, resource information such as the CPU, memory, and storage of the hardware server can be collected, and the deployment ...

The invention relates to a balanced deployment method and device for a virtual network function. The method comprises the steps that resource information of each server and functional information of various to-be-deployed virtual machines of the virtual network function VNF are acquired, according to the functional information of the various to-be-deployed virtual machines of the VNF and the resource information of each server, the various to-be deployed virtual machines are dispersedly deployed to the corresponding servers, so that various virtual machine deployments of the VNF are balanced.According to the balanced deployment method and device for the virtual network function, an overall consideration is carried out from a VNF angle, according to the resource information of the server,and the functional information of the various to-be-deployed virtual machines of the VNF, the various virtual machines are deployed to different servers, the balanced deployments of the VNF virtual machines are achieved, uniform utilization of underlaying hardware resources is considered, the disaster recovery safety of the VNF is fully considered, the virtual machine deployment is carried out from the VNF angle, a range of virtual machine mutex can be reasonably set, and then the failure rate of the virtual machine deployment is reduced.
Description
technical field [0001] The present invention relates to the technical field of communication services, in particular to a method and device for balanced deployment of virtual network functions. Background technique [0002] The underlying hardware of NFV (Network Function Virtualization) realizes the sharing of hardware resource pools through openstack virtualization technology. NFV framework such as figure 1 shown. [0003] The entire NFV architecture can be divided into three layers. Among them, NFVI (NFV Infrastructure, infrastructure for network function virtualization) is a resource pool from the perspective of cloud computing, which converts physical computing / storage / switching resources into virtual computing / storage / switching resource pools through virtualization. VNF (Virtual Network Feature, virtual network function), VNF corresponds to the current telecommunication service network, each physical network element is mapped to a virtual network element VNF (Virt...
